First weekend out was 9/2 and 9/3 at
Willow Springs International Raceway. The weekend started off rather slow, as I ran in the yellow (beginner) group the first couple sessions to learn the line, get reacquainted with driving on the track, and to learn the new setup. However, by the afternoon, I was back in the blue (advanced intermediate) group and was setting fast lap every session. I was amazed at how well the car handled straight out of the gate. In my first session, I got metal-to-metal contact between the front wheel and the GFL a-arms in the entrance to turn 5, where I'm braking, turning and hitting a dip all at once. Stiffened up the compression damping to 7/8 and the rebound to 7/8. Car immediately felt absolutely perfect.
Using the pyrometer, I kept adjusting tire pressures until I got even stagger across the face of the tires. This sweet spot came at 37psi front, 35psi rear. Tire temps that weekend were insane. I saw over 225F several times! The Nittos were great. Tons and tons of grip (a lot of that is due to the certifiably insane tire sizes I am running). They are very predictable near the limit, although greasiness comes on very very quickly, and if you're not ready for it, you go shooting off the inside of turn 4 sideways and mess up all sorts of stuff...
Saturday's times were decent, but nothing special. I ran 1:37s and Richard who drove it for one session without pushing it too hard, did 1:38s. Sunday, I really figured out the course and started to gain enough confidence to push the car hard. Turn 2 is flat out in that car with the mongo tires and huge wing. I would lift a split second to settle the car for turn-in, and then stay flat out all the way around, tracking out around 90mph. Turn 9 of course takes lots of practice to get right, but I got my apex speeds up to 96mph. This was good for a 1:35.4. Aaron Bitterman drove the car for a half session, laying down a new street s2k record of 1:33.8. He had nothing but good things to say on the way the car handled. I'm sure I lost all that time in turns 3-5.
After the big off in turn 4, the steering wheel was off center, the fender was banged up, the bumper was melted, the tire was cut, so it was time to fix the car again. Took it into Marty at Honda of Pasadena to fix the suspension/alignment. Unfortunately, he couldn't find the source of the problem and could only align the front left to -3* camber. After the alignment, the steering wheel was centered, but quickly went back off-center, and the car started pulling hard to the left. However, it was too late to get it fixed again before the SpeedVentures World Champioships at
Buttonwillow 9/29-10/1.
Buttonwillow has always been my favorite event of the year. I did it in 2003 on street tires and stock suspension on my way home from having the Elda rollbar installed by Comptech in Sacramento. In 2004, I shared a garage with Richard and John, and brought my brand new truck filled with half-used Hoosiers, Kumhos and then bought a set of RA1s from the buttonwillow tire shop. At the time, I was convinced my stock suspension was garbage and Richard helped me install his take-off stock shocks to compare against. Now, I know the problem I was experiencing was bumpsteer. Needless to say, that experiment was a waste of time...
Anyway, flash forward to 2006. This weekend, the entire new crop of fast guys was there. None of the old guard were there, unfortunately. Rylan and Richard were doing an SCCA race at Laguna Seca. Will's car is still being put back together. John is taking a hiatus. Dave sold his car to Richard. But, it was a great time running against Rob, Kel, Raymund, Tim, Sri, Chris and others.
Friday was again a time to get reacquainted with track and car. The car didn't work nearly as well here as it did at Willow Springs. I had a hard time getting it to take a consistent set. Friday, I didn't play with settings too much, as I was trying to work on the line more than anything. I did soften up tire pressures, and softened up front rebound. Saturday, I stiffened the swaybar to full-soft on one side and middle setting ont he other side. I reduced rear compression damping to 6/8. The car was more predictable, but the tire pressures dropped to 32F/30R hot, and they seemed to get greasy after just a couple laps. Sunday, I raised the tire pressures all the way back to 37/35 and softened up compression to 5/8. Buttonwillow is very bumpy and the car responded pretty well to softer settings. Sunday, the car felt very good, and I felt like I had the line down pat and had my fear turned off.
Session 3 was almost perfect. I hit all my apexes, naturally drifted to the edge of the track on corner exit, kept my foot planted when necessary, but fuel starvation killed all of my laps. So, I pulled off to top off the gas and started hearing this ominous tick-tick from the right rear wheel. I took the car to all the other S2000 owners and asked their opinion on the noise. Some thought it was a CV joint, others the diff, others the hub, and others the wheel bearing. Any of the 4 would have made the car undriveable on the track, so I packed up and headed home early, without a decent time. By the time I got back to Pasadena, the noise was a constant scraping/grinding noise and the diagnosis was set: wheel bearing.
Fri: Rob 2:01.9, Me: 2:05.4, Kel: 2:06.x
Sat: Raymund: 2:07.0, Me: 2:07.9, Kel: 2:08.3
Sun: ?? I only got to a 2:07, but 2:05 was extremely doable with a working car.
This new class of modified street s2000s is fast, and their drivers exceptional. Rob is clearly the one to beat, and I intend to do that... soon :)
