super stock or thunder stock


Recommended Posts

Can any one give me some basic info on converting a imca hobby stock or I-stock dirt car to run on asphalt? what kind of changes need to be made to front suspension, caster/camber, toein, shocks, springs, ETC.... any and all comments or information would be greatly appreciated. The dir cars are set up to run on 1/4 and 3/8 mile banked clay tracks thanks for the help!

These settings are totally out of my butt since I have no idea what your car is or weighs or is configured like, but here's a wild guess:

 

3-4 inch front roll center height

 

1/8" - 3/16" toe out

 

zero ackerman, but a small amount of roll steer (bump steer) in the toe-out direction

 

3+ degrees of RF negative camber 1-2+ degrees LF positive camber. Use your tire pyrometer to get better camber settings.

 

1 degree positive caster on LF, 3+ degrees of positive caster on the RF

 

You probably want to keep the LF down as long as you can, so the LF shock should have a high rebound number

 

Springs.. well, since I have no idea what motion ratios you have in your a-arms, I'd be giving you a wild guess. If you know the corner weights of your car and the motion ratios of your a-arms, I can ballpark guess your front spring rates.

1985 metric monte carlo that is currently set up to run IMCA I-stock rules... did not know how much i would have to change in setup to switch to asphalt.... may run at RED RIVER Speedway or maybe come down at times to Kyle, TX
