I started racing there not too long ago and have a decent setup now. I have blue front and silver rear springs with 40wt oil. Shocks mounted in the middle hole of front and rear shock towers. Standard sway bars front and rear. About 1 degree of camber all around, 0 toe in the front, 2 degrees toe in the rear. 6 degrees caster (probably too much). Using 32/100 gearing with 64 pitch gears and a Mazda 6 body to top it off. I started with a front diff and later went to a front one way. It seems this track likes a front one way. If you are just starting you should keep the front diff for a while though. Its very different driving with a one way and it eats parts if you crash.
