Thank you guys,
M4A1mustang: We contstantly try to tune out the understeer, we've tried a few things even, 285's square wich solves this but I prefer the steering responce of the smaller rubber up front. As the car sits we have it almost completely netural, w/ a touch of oversteer as I prefer. But Autoclub has a few slightly off camber turns that we can't do much about w/o sacraficing grip in other areas of the track.
Spearfish25: We run Hankook RS3. 265/285. Per Class Rules we are premitted to run a few options but must be DOT Street tire with a certian treadwear #. NT05, RS3,ect. Tires like Advan Neova were deemed too fast. RS3 is the best of the batch IMO. Tire size per class rules can't exceed 285' width also. I'd love to see what she can do with some R-comps or Hossiers.
P.S Thanks for posting the vid in the tread!
