davepull, you let the cat out of the bag on McMasterCarr.com

i get lathe bits from them & sell for $10 at the track

anybody tried the diamond bits they sell?
proficar, try 4degrees caster and 0 anti-dive for foams & reg diff on carpet. i haven't done the rear shock tower yet either but will try soon. also with foams you can run 1degree rear toe. use the "F" block in rear with the "R 2+2" or "R 2+0". some guys use the losi uprights to run 0degrees
