CarSpace The Outside LineIn motorsport, passes made on the outside are always cooler and more breathtaking! Welcome to my blog about automotive-related things...and some that are not. Sep 9, 2009 - Jim Hall Karting SchoolHi, everyone! Here's a video of me driving on Jim Hall Karting School's "B" Course. I attended the school back in May. The courses I completed were the Day 1A and 1B classes. Enjoy!
Apr 21, 2009 - Shell nitrogen-enriched gasoline: Don't believe the hype
I'm sorry I haven't blogged in awhile, folks. Honda's latest advertising campaign highlighting the low cost of ownership for eight of their ten vehicles (Accord, Civic, CR-V, Element, Fit, Odyssey, Pilot, Ridgeline) has been extremely demanding at work. By now, many of you have seen Shell's commercials for their new nitrogen-enriched gasoline. We've made a great product even better! The experts at Shell have found a way to destroy gunk with all three grades of Shell gasoline! Every drop of Shell gasoline contains a NEW Nitrogen Enriched cleaning system that seeks and destroys engine gunk in both conventional and modern engines. There's nothing else like it! What makes NEW Shell Nitrogen Enriched Gasolines even better? -A unique, patented, improved formula exclusive to Shell designed to seek and destroy engine gunk. -Acts as a barrier to help keep your engine clean and protect it from performance-robbing gunk even better than before. -Helps protect and clean critical engine parts in all three grades of Shell gasoline with the most advanced Shell technology ever. -Helps improve engine performance as you drive. -Has been extensively tested, clocking more than a half-million miles in various engines and vehicles, covering a wide range of conventional, modern turbo-charged, direct fuel-injected and hybrid engines. I asked Edmunds.com Engineering Editor Jason Kavanagh what, if anything, was special about Shell's new gasoline. He said he believed that nitrogen was used in most detergent gasolines. After learning that, I went to Chevron's web site to see if their gasoline was also nitrogen-enriched. Sure enough, it is. Here's their spiel: http://www.chevron.com/products/ourfuels/chevwtech/ Chevron gasolines with their nitrogen-enriched Techron additive contain polyether amine (PEA) chemistry to help keep vital engine parts cleaner than lower quality competitors, helping reduce the amount of hydrocarbons, carbon monoxide and nitrogen oxides released into the atmosphere. It all adds up to a cleaner and happier car.
Mar 15, 2009 - Revenge of the 'Rex
In November 2007, my first trip to Laguna Seca Raceway didn't quite go as planned. Since that time, I thought the place owed me one until I could make my return. I say the place owed me because my mistake of running over the Turn 6 apex marker like many others didn't seem that egregious. A mid-January discovery of an open track day on February 25th with the Green Flag Driving Association (through MotorsportReg.com) paved the way for that return. The weekend before the track day, I got a new set of Dunlop Direzza Sport Z1 Star Spec tires (P225/45R17 90W) (nuts...the Tire Rack has a $50 rebate on these right now until March 31st if you buy a set of four) mounted and balanced. Before putting the new shoes on, I changed the front and rear brake pads from the EBC Red Stuff Ceramic pads to Ferodo DS2500s. I didn't change the rotors because I just replaced them the previous month with the EBC pads. And thanks to the Motive Products hydraulic brake and clutch pressure bleeder I got from RallySportDirect.com, I was able to bleed brake fluid by myself for the first time using a fresh 500 mL bottle of MOTUL RBF 600 high temp fluid.
After unpacking the car, adjusting the Koni strut inserts to nearly full stiff in the front and 1/2 stiff in rear (the latter required the removal of the rear seat (six 12mm bolts) to access the tops of the rear struts), mounting a video camera to the rear windshield, and slapping on some magnetic numbers purchased from izoomgraphics.com onto the front doors, the car was ready to hit the track. I was assigned #16 because my last name was probably sixteenth on the alphabetical list of people registered for the intermediate group at the time the numbers were determined.
I naturally used the first session to get re-acquainted with the track. After three or four laps, I figured out the braking points and lines I wanted to use. As I approached Turn 6 for the first time, I felt a little apprehensive, but knew it was time to exact my revenge! I drove through and took a mental snapshot of the turn to refer to when approaching it every lap. Above is the video I recorded in the first session. I spent much of the early part of it following a Nissan GT-R whose driver appeared to be learning the track. Later in the day (Session 7), I let him by to see how well (or poorly) I could keep up with him/the car. He checked out on me in about half a lap! The 'Rex and I could hang with him in the turns but didn't have the beans to remain in touch on the straights. At the six minute-mark, I let a Porsche 911 997 GT3 RS--just like Chris Walton's favorite car--blow by me going up the Rahal Straight. Soon after, you'll see me get mired behind the slowest S2000/driver combination ever (they make another appearance at the 21:00 mark, too)! I don't know what was going on with them throughout the day. However, I will give the driver of the S2K (black helmet) credit for seeking instruction later in the day (evident when the car was on the track with two people with him riding shotgun). The only allowed passing zones for the beginner/intermediate group that day were the front straightaway, the stretch between Turns 4 and 5, and the Rahal Straight. As the first session progressed, I felt the rear of the car was too soft. After the session was completed, I stiffened the rear Koni inserts and also reinstalled the rear seat bottom. Its absence explains the clicking and clacking heard in the video above when the seatbelts were moving around in the turns.
Session Two had the distinction of being the only beginner/intermediate session with an incident. A first generation Mazda Miata somehow found its way into the kitty litter (gravel trap) on the outside of Turn 11. To begin the session, I left the pits behind a Ford Mustang (A GT350 replica? Kurt or JDP can definitely enlighten me here.) that let me by at the end of the first green lap. Two laps later, the session was stopped to get the Miata out of the sandbox. Once its wheels were back on the tarmac, it was able to restart and return to the pits using its own power. After the session resumed, I had the sheer pleasure of catching and receiving a point-by from a (stock?) Mitsubishi Lancer Evolution X GSR a little less than 10 minutes after I left the pits. Two of the faster cars I let by in the session were an ex-Bondurant school Ford Mustang (Cobra?) and a Porsche 911 (997 Carrera S?). The third session began with me leaving the pits behind an older Porsche 911 (964? 930? Little help here?). I had even more fun chasing this car than reeling in and passing the Evo in the previous session! The fun lasted until the 8:30-mark when I got stuck behind a 996 Turbo Convertible. The person driving it was nice enough to let me by between Turns 4 and 5, but the other 911 had already checked out by then. During this session, I determined the car was a little more squirrelly than I'd like when transitioning from an on-throttle state onto the binders. As a result, I softened both of the rear Konis a smidge after I had returned to the paddock. The most enjoyable things I worked on over the course of the day were trail-braking and figuring out how to get through the Rainey Curve (Turn 9) well. I found I could work on the former most when braking for the Andretti Hairpin (Turn 2) and Turn 3. Almost every time I drove through Turn 9, I remembered Josh Jacquot's advice not to lift when driving through it. Since I'm a) not as skilled as Josh and b) not driving whatever rocket ships he may have driven at Laguna Seca, I would usually go to a partial-throttle state when driving through the turn. For some odd reason, I seemed to feel more G-loading when driving through Turn 9 this time than my first track day at Laguna Seca. Because of that, I figured I consistently carried more speed through there. Session Four provided me with the most clean laps out of all the sessions I drove that day. Because of that, I probably turned my fastest laps during it (no timing transponders were available for rental that day). I suppose I could extract each lap's time from my recordings, but that would be inaccurate and take a long time. I'm guessing I turned faster laps compared to my first trip because of the upgraded suspension components (JDM STI springs and Koni strut inserts) I had this time. During this session, I also had the pleasure of feeling I had the car's setup totally dialed in as it responded to all of my inputs in the way I hoped and expected. The driver of the 2005 Subaru Impreza WRX STi I caught and passed told me he had been experiencing brake fade the entire day. His car was also shod with Dunlop Direzza Sport Z1 Star Spec tires (although his tires were 245-width) and stopped by Ferodo DS2500 brake pads. My car was using the stock rotors whereas his car was equipped with DBA 5000 two-piece rotors. I think he was using the ATE Super Blue brake fluid. The Direzza Sport Z1 tires held up great on the track. They didn't seem to provide as much ultimate grip as the Bridgestone Potenza RE-01R tires, but definitely didn't wear as much either (perhaps a visual confirmation of its 200 treadwear rating compared to the 180 rating of the RE-01R). Adhesion felt consistent throughout each session with no signs of becoming greasy or going "off."
At the end of the fourth session, I heard a scraping sound coming from the rear. A closer inspection revealed that I had used up the left rear brake pads. Not wanting another track day at Laguna Seca to come to a premature end, I donned a pair of gloves and began one of the quickest brake pad changes I had ever performed. The change would've been even quicker if I didn't have to be careful handling the hot pads' backing plates. Now you may be wondering how I used up the rear pads before the fronts. The front brake pads were a new set of Ferodo DS2500 pads. The rears, however, were used for my track days at Buttonwillow Raceway and the Streets of Willow Springs in March and April 2008, respectively. I thought there was going to be enough pad material left to get me through the day. I obviously thought wrong. The rear brake pad change was completed in about 40 minutes. I missed half of the fifth session, but was glad I could enjoy the rest of the track day. I didn't bring any spare rotors with me to the track. But I didn't care. I was determined to turn more laps even though the rotor had been warped and scored. The vibration produced by the rotor was quite significant, but braking effectiveness seemed largely unaffected.
Another issue that arose in the afternoon was the beginning of the demise of the tranny's fourth gear synchro. With 108K (hard) miles under its belt, the transmission has served me well. Upshifts over 4,500 RPM from third gear to fourth gear began producing a light grind sometime during the fifth session. I began shifting more deliberately and making sure I was shifting "straight" and not "diagonally" to see if things would improve. They didn't. (I got a quote of $1,200 for synchro replacement the next day. I'll probably just live with this for the time being and try to drive more conservatively...at least in third gear anyway.) Sessions Six and Seven were pretty much more of the same. Because only 30 cars registered for the event, the organizers thought it would be good to combine the beginner and intermediate groups. I was initially concerned when this was announced in the morning drivers' meeting. An upside of the merge, however, was that everyone would get more track time. The original plan was to run five 25-minute sessions. The new plan allowed for six 25-minute sessions and one 15-minute session. At the 11:20-mark in Session 7 (see video above), I let the Nissan GT-R by me on the Rahal Straight. Watch as it runs away from me by the end of the lap! Near the end of the session, I didn't drive as well and started to get a little sloppy. After the session was done, I deemed myself fully satisfied with the day and felt exhausted. It had been a great day!
A full gallery of the day's photos can be seen here: The other videos from the day can be seen by viewing the "More From User" and/or "Related Videos" in Google Video. That's all for now (especially since the 'Rex has an ailing tranny)! I would love to hear from others about their open track day experiences! Or if you'd like more info on tracking your own vehicle, I'd love to help!

Feb 10, 2009 - Debris owned me
On the night of Dr. Martin Luther King, Jr. Day (Monday, January 19, 2009), I drove over a piece of debris on the 10 East while I was passing through Downtown Los Angeles and approaching the East LA interchange. During my drive to work the next morning, I noticed a white 2005-2007 Subaru Outback 2.5i in the adjacent lane to my right slogging through traffic on the 60 West with me. A minute or two later, he honked his car's horn to get my attention. I put the right front window down for him to tell me the right rear tire was flat. Love. It's what makes a Subaru, a Subaru. This notice completely surprised me because I did a quick walkaround (with a flashlight) when I got home the previous night looking for damage. That "inspection" was prompted by a loud bang I heard from the left front when I ran over the debris (remains from an accident?). I was really surprised the right rear tire had been affected. As displayed above, the right rear tire's sidewall had been slashed. By the time I pulled the car off the freeway and stopped, the air pressure reading I took showed 0 psi. I was impressed with how well the tire's sidewall supported the weight of the corner and prevented the car from riding on the wheel/rim. Also surprising was the fact that I didn't perceive that the tire was low. After stopping the car in a Jack-In-the-Box parking lot, I took out the 12V comprossor than came with the emergency kit I bought a while ago from the Tire Rack. Minutes later the tire was now at 37-38 psi. With air in the tire, I completed my morning commute to work. I measured the tire pressure again when I got to work and saw that it was still around 37 psi. I decided to take the car to Stokes Tire Pros. during my lunch break for a closer inspection. There, a technician noticed the gash in the tire's sidewall. Jack presented me with my options and I drove back to the office. My plan was to order a replacement BFGoodrich g-Force Super Sport A/S tire (P215/45R17) from the Tire Rack (I only needed one because the left rear tire was still relatively new) and have it drop-shipped to Stokes. While waiting the two days for the new tire to arrive from the Tire Rack's distribution center in Reno, Nevada, I thought it'd be okay to use my full-size spare tire. The gash in the sidewall was amazing in the sense that it usually remained closed which allowed the tire to retain its air. The tire didn't lose any air over the course of my trip home! I swapped my full-size spare tire, an old Bridgestone Potenza S-03 Pole Position P215/45R17, with the right front tire and moved the right front to the right rear. Why didn't I simply put the spare on the right rear corner? As a former summer/track tire,I knew the spare had a lot of wear on it (I prayed it wouldn't rain) and thus, wouldn't have a circumference similar to the left rear tire's. Having different circumference tires on the rear corners could potentially overwork and damage the rear (limited-slip) differential.
In 9-1/2 years of driving, I had never lost a tire to a nail, screw, or other road hazard. It was that thinking that led me to think I would be okay without the Road Hazard warranty the Tire Rack offers. Now I'd think twice before passing up on the warranty again for my next set of street (read: primary use) tires. On one hand, it'd be great to have that protection and peace of mind. On the other hand, the coverage isn't worth it if it'll be another long time until I need to replace a tire or tires due to unforeseen circumstances.

Dec 27, 2008 - Merry Christmas & Happy New Year, 2008 LA Auto Show highs
Merry Christmas and Happy New Year, everyone! It's been awhile since I last wrote here. I hope all of you are doing well. This blog entry is a few weeks late but I thought I'd share some of the vehicles I really liked at this year's Los Angeles International Auto Show. Mazda MAZDA3 Some people hate that the new MAZDA3 looks like it's smilling. I love it! I'm still not too keen on the plastic above the fog lights, but that may grow on me.The new 3 will hit Mazda showrooms this spring in sedan and hatchback form. That said, I still highly recommend the current MAZDA3 as the best compact car one can get right now (if all-wheel drive is not needed). Honda Insight Seeing the Honda Insight Concept in person made me think, "I wouldn't mind being seen in that." Honda's upcoming Toyota Prius-fighter looks cool and maybe even fun-to-drive. Shortly after the LA Auto Show, photos of the production version Insight were released.
To stay informed about Honda's new hybrid, make sure you check out Edmunds.com Inside Line's Honda Insight Buzz Station page. Five Axis Lexus GS 460 The more I see flat (i.e., not glossy) paint on vehicles, the more I like it. This Lexus GS 460 modified by Five Axis looks great. But I think what Five Axis did to a Lexus IS F last year looks even better.
2010 Ford Mustang Meh. As far as pony cars go, here's what I think. Chevrolet Camaro > Dodge Challenger > Ford Mustang 2009 Porsche Boxster and Cayman Very nice! I've got a feeling Devoted Dan, my 2004 Subaru Impreza WRX Sedan, won't be able to keep up with these on the track. Also new for MY2009 is Porsche's dual-clutch automated manual transmission called Porsche Doppelkupplungsgetriebe, or PDK for short. Reviews of Porsche's new gearbox have been positive except that the tranny's interface via steering wheel-mounted buttons or the shift lever are counter-intuitive. Ferrari 430 Scuderia Wow! Forget the Ferrari California shown below. The 430 Scuderia was my favorite Ferrari at this year's show.
Aston Martin DBS Absolutely beautiful. However, I think Aston Martins look best in Silver or British Racing Green. Lotus Evora I like Lotus' new 2+2 more than the Elise and Exige. In fact, I like it so much that I went and got one...in Gran Turismo 5 Prologue for the PLAYSTATION3 (PS3). Volkswagen Jetta TDI Cup Race Car I think the 2009 Volkswagen Jetta TDI is a pretty neat car. So does Edmunds.com, which currently has one in its long-term vehicle fleet. What many of you may not know is that there is a Volkswagen Jetta TDI Cup racing series here in North America. The above car is an example of a Jetta TDI Cup race car. The use of Audi R8 front brake calipers is interesting and a little funny, too. MINI John Cooper Works I've never driven a MINI Cooper. Hopefully, I'll take one for a spin sooner than later. Rowing through the gears of this MINI John Cooper Works (JCW) Hardtop impressed me because of the shift lever's positive feel through the gates and short throw. I wish all BMW manual transmissions, which tend to have long shift throws, felt like this. These are the cars I really like during my brief time at this year's Los Angeles International Auto Show. I hope you all enjoyed my highlights. As 2009 approaches, I think it would be nice to leave you all with one of my favorite moments of 2008. My trip to Buttonwillow Raceway in March resulted in a 0.470 second improvement over my previous best lap time of 2:12.215 on Buttonwillow's Configuration #13 clockwise. My lap of 2:11.745 is the first lap shown in the YouTube video clip below.
Dec 4, 2008 - The sting of blingAt this year's Los Angeles International Auto Show, there were some factory-modified vehicles that some brands prominently displayed. Hear are a few of the atrocities my eyes (and camera) couldn't resist. 2009 Ford Focus Coupe Now, let's compare the Focus above with the 2009 Ford Focus RS hatchback available in Europe.
2009 Toyota Venza The 2009 Toyota Venza is Toyota's all-new wagon/crossover born with an identity crisis. For the most part, it's basically a Camry Wagon. On the other hand, it also shares components with the Highlander. The sad thing is "dubs" (20-inch or larger diameter wheels) come standard on factory stock V6-powered Venzas.
Here's what I think of all of these: Next week, I'll share some of my favorite vehicles featured at this year's LA Auto Show.
Nov 26, 2008 - How I equipped my car with 12 tiresHappy Thanksgiving to everyone who reads this! What are you most thankful for? Why select an all-season tire in (Southern) California? Or rather, why not? First, I have a separate set of Bridgestone Potenza RE-01R (P225/45R17 91W) extreme performance summer tires that I use for the track. Second, I like knowing that my car can be driven in snow if necessary to go snowboarding, skiing, or to retreat sites. Third, it would be nice to have a set of tires that last for a while compared to summer tires or even the factory supplied Bridgestone Potenza RE92 tires, which only have a treadwear rating of 160 compared to the BFG's 400. So how exactly did I equipped my car with 12 tires? The answer is I didn't. But in a way, I did. BFGoodrich's g-Force Super Sport A/S tire replaced the venerable g-Force T/A KDWS. The g-Force Super Sport A/S is constructed with three distinct rubber compounds to provide traction in dry, wet, and snowy conditions. Many all-season tires may have three distinct zones, but each zone uses the same rubber compound.
Dry: The outer sides of the tread feature large shoulder blocks designed to maximize traction while cornering. Additionally, these same blocks also contain sipes to aid with acceleration and braking in snow. Displayed in the middle, the continuous center rib provides the driver with excellent steering feel. Wet: The center rib and grooves on its sides work with the swept lateral grooves to effectively channel water and reduce hydroplaning. Snow: In-between the dry and wet tread zones is the snow zone. Working in conjuction with the outer shoulder blocks' sipes, the intermediate tread block provides a snow hook shape to function like snow chains. You don't have to take my word for it, though. In May, the Tire Rack conducted a test of the BFGoodrich g-Force Super Sport A/S tires against its chief competitors. You can see their results here. Although it finished second in their comparison, the g-Force Super Sport A/S produced the dry performance numbers. It didn't have the wet grip of the Bridgestone Potenza RE960AS Pole Position tire (another tire I was considering at $150 each) or the ride comfort, but I figured most of the miles I would accumulate would be on dry tarmac. Thus, I decided to sacrifice road manners for better handling (after all, I'm still young, right?).
If that's not enough to convince you of what an excellent tire this is, Car and Driver also plays host to a BFGoodrich Tires Virtual Test Drive (Adobe Flash required) mini-site. There you can learn more about BFGoodrich tires including the g-Force Super Sport A/S. Four-time SCCA Trans Am champion and host of SPEED Test Drive and SETUP, Tommy Kendall, will talk, or rather, drive, you through the features and construction of the tire. You can even ride along with Tommy as he drives a Mitsubishi Lancer Evolution IX on the track at Miller Motorsports Park. Here's a cool did you know (dyk): BFGoodrich is owned by Michelin (FRA) like Firestone (USA) is owned by Bridgestone (JPN) With old man winter upon us--or right around the corner--there isn't a better time than the present to make sure your vehicle's shoes will keep you and your loved ones safe in inclement weather. If your tires' tread depths are less than 4/32 of an inch you should consider replacing them as soon as possible. 2/32" is the legal limit, but grooves shallower than 4/32" are less resistant to hydroplaning. Not sure how to measure your tires' tread depths? Here's an excellent article you may find useful. Remember to keep your tires properly inflated as well! Tire Rack: Measuring Tire Tread Depth with a Coin
Nov 18, 2008 - Cupholder evolution: Behold the GPS-holder
Last month, I purchased a refurbished Garmin nüvi 680 from Amazon.com for $199.99. Knowing it's illegal to mount the portable navigation unit on my windshield using the suction cup mount*, I knew my creativity would be needed to mount the GPS unit. After studying the dash a little bit, I realized the cupholder could serve as an excellent GPS-holder.
I'll be the first to admit the MY2002-2004 Subaru Impreza dash cupholder's design is less than stellar. It seems like it was an afterthought when the interior was designed. The only positive thing about it is that it could hold larger circumference bottles and cups than the cupholder next to the handbrake. For MY2005 (to MY2007), the interior of the Subaru Impreza was slightly redesigned and this cupholder was deleted. Instead, an additional cupholder was added next to the handbrake. To mount the nüvi, I connected it to its suction cup mount and laid the nav unit plus the mount in the cupholder. The fit seemed decent but the unit would still move around quite a bit under hard braking or acceleration. The solution? A rubber band placed around the mount and cupholder clamped the nav plus mount assembly down securely. Doesn't the unit look secure in the first photo above? Its silver finish also works well with the color of the dash, too. :o) *NOTICE TO DRIVERS IN CALIFORNIA AND MINNESOTA: State law prohibits drivers in California and Minnesota from using suction mounts on their windshields while operating motor vehicles. Other Garmin dashboard or friction mounting options should be used. Garmin does not take any responsibility for any fines, penalties, or damages that may be incurred as a result of disregarding this notice. (See California Vehicle Code Section 26708(a); Minnesota Statutes 2005, Section 169.71)
