I just need a base setup for carpet so I can go from there.


BTW. is there a one way diff for front?
Paragon is a good choice but the stock tires are your main culprit. Get you some good race slicks. The Atomic tires are working great for me along with their inserts. HPI X pattern might be ok as long as they are belted and have a good compound mix.

Front,
pink spring
70wt oil
3 hole piston
hpi shock tower outer hole
spacer under upper inner links
heavy spring in the diff
lower inner hinge pins angled up (anti dive)
5mm ride ht
1 deg camber

Rear,
Gold spring
30wt oil
3 hole piston
hpi shock tower inner hole
upper inner link in lower hole
medium tight diff
stock lower inner hinge mount
5mm ride ht
1.5deg camber

Remove the sway bars until you feel your car is dialed. Once the car is working perfect you can then add sway bars. I never use them though.
Long wheel base= more stable (pushy)
Short wheelbase = quick turn in (twitchy mid corner)
Exotek mini wing- a must
CRX chassis = DIALED!


Good luck! Mike
