I have run Chuckwalla several times this spring. One of those days was CCW. So, I feel quite familiar with the track. I have been out of racing for 12 years. These track days along with a day at Auto Club, Streets of Willow, and Buttonwillow, have helped me familiarize myself with the car.
The last track day, on March 23rd, I had added a K and N air filter, Whiteline crossmember mount insert bushing, Whiteline gearbox bushing, SS brake lines, Motul 600 fluid, Ferodo DS 2500 brake pads front and rear, the Nameless exhaust, including front pipe and over pipe, Wedsport TC105N 17x8, Michelin Pilot Super Sport 225x45x17 tires, and a Grimmspeed Master Cylinder Brace. Granted, I had an exhaust leak, but as much as I had hoped it slowed me down, it was just my driving skill. My best time was a 2:17.9.
The next day, at Chuckwalla was this past Sunday with the Ohlins just installed Friday. I was there on April 21st and ran only one session, due to the unfortunate accident. We also installed Whiteline anti-dive caster correction, Whiteline front control arm bushings, and Whiteline rear camber adjuster kit, which gave us an extra -.5 degree camber, in the rear. I ran a straight pipe and removed the exhaust. I do not have any tune. This resulted in a best time of 2:11.2. These last modifications were the only differences from the previous best time and resulted in a 6.7 second improvement. Since I lacked experience with the new set-up, I ran the tire pressures too high, which should result in some improvement. I need to dial in the rebound settings and I also have a lot to gain with better driving.
I believe that the majority of improvement came from the Ohlins. Unless of course, I became a much better driver, in a few weeks!
