A super-dialed smooth carpet setup for RC12L3/4. (Aggressive on power steering, neutral off power and perfect traction balance):
REAR:
Jaco Grey Tires
.075 "Thick" T-Bar
50wt shock oil
Red shock spring
Niftech Teflon damper puck discs
Front:
Jaco Purple Tires
5-degree upper-arm mounts
Both caster shims to the rear
.022 springs on kingpins
1-degree negative camber
0.5-degrees toe-in
BE SURE TO DIAL IN SOME NEGATIVE EXPONENTIAL ON STEERING! After you dial her down via radio, she's ready to tear up the track if you have enough motor...
Give this setup a shot if you want a very aggressive yet still sane car.
