We tested at the Streets of Willow last Friday. Needless to say the car is amazing and incredibly fast. We only did about 15 laps but got down to a 1:21.9 which is 2 seconds a lap faster than Edmunds tested the Corvette ZR1 around the same configuration.
Right now the only suspension modifications we have are a set of the Eibach Pro-R2 coilovers and a set of their sway bars. All the bushings are stock as are the control arms. We had a bit of understeer to combat with early in the day but we got most of it dialed out with shock adjustments and tire pressure. We are going to be running a 265 in the front at our next event instead of the 245 we have right now which should hopefully help.
We have some video of the testing and once it is edited I will post it.
