I went out the first session and practiced. It felt good, but I noticed that I was pushing the front a bit. I was still going slow, what's up? So we added some preload to the front and I went back out. Still going slow, front is better but still pushing.
*wait* I wasn't going slow. Senses were wrong. According to my lap timer I just clocked a tenth of a second faster than I had ever gone at Infineon before (on the SV). Wow, all my senses were off.
We ran out of preload adjustment on the front, so we tried various compromises with the rear suspension but nothing really paid off. I did an emergency run down to San Jose where Evolution Suspension had the strongest rated springs in stock, and we rebuilt the front end Wednesday morning.
All better, going faster, right? Uh... not so much. I was back within a second, but this was my 7th day on these tires and they really started to give it up on me. I rode around and did convincingly consistent lap times about 2 seconds off my best pace trying to manage the tires. But by 4pm I was losing the rear everywhere, and had to give it up and come in.
It's hard to leave a 2-day event like this, with a major upgrade like that, and not have some nice new lower lap time to show for it. I do feel stronger, and I did get some things worked out, but it's all vaguely unsatisfying. We'll have to see what we have at Buttonwillow next Friday.
