I run at Big Boys Toys in Taunton, MA, and its pretty big and flowing (track pic: http://www.bigboystoyshobbies.com/big12track.html
Alot of guys from speedmerchant actually run there weekly (eric, jake, bruce, david, scott...) and normally they run (or at least suggest for me to run
) purple fronts, gray rears for stock and whites for mod, orange side springs (although i think some of them might of gone stiffer), the speedmerchant black center spring for the shock, not sure for front springs, i am just running stock right now, and i am currently using normal weight fluid in the damper tubes.
for high bite though i would maybe try blue or one stiffer (white?) side springs, and the .20 fronts probably should be good, if you run mod i would check out the new trinity granite tires, since they are basically white rears with a stiff outside (similar to plaids for TC's), but in stock they have way to much grip, even with a relativly green track.
although the way your car is currently set up it should get around pretty well, but trying different stuff never hurts, good luck!
