I've since started doing track events with the SCCA Tracknights across America. For $150 it's a ton a fun to get (4) 20 minute sessions out on a track to really see what the FiST can do. I knew this car was good, but I'll tell you there were a lot of people in their Porsche's and Corvette's who must have been embarassed to see the FiST run up on them and then pass and run away. The trackday experience did point me in the next modification direction very clearly though... Brakes and cooling! In 85 degree ambient temps I would get water temp light after about 15 minutes. It cooled down quickly with 2 slow laps, but it sucked having to slow down to cool the car.
I look forward to the next event on 22 July now that I've taken care of the brake issue. I got the Wilwood 12.2" big brake kit with Polymatrix B pads... Holy SH*T does this thing stop now?
