I have been running my B4.1/2 three days a week for about the past four weeks at the local track. I have ask all the fast guys about their set up as far as tires and shock oil and pistons and foams and battery position. I have come to the conclusion that not everyone's setup will work for me, even with their best efforts to try to help. In the last week I stopped banking on what works for everyone else, and started to learn what works for me and my driving style by trial and error. Granted i'm not running the same springs or times as the fast guys but I shaved about two seconds off of "my" lap times in a week.
I appreciate everyone's help at the track greatly, but I feel I used their info to help me learn more about my car and how to tune it in the right direction.
