yes, this is the dirt oval racing forum.....what was it you wanted to know?

hey basket thanks for responding

iam tryin to find out on caster .. top of king pin to the bottom king pin .. why run like 20 or 15 deg caster on frame .. and say not flat on frame n put the caster in the c block ?

and if so would say 10deg caster be good or say 15deg on the c block .. custom works 15deg c blocks ??

thanks for any ideas or help on this ^5s

Fire Doc I cannot answer that. I would contact Todd Putnam. He has lots of information about chassis.

Before we can answer that we need to know what car you are running . As the castor you run depends on the chassis .

Quick answer: The castor used to angle the A-arm is used to absorb imperfections in the track (bumps, holes, etc). Take an offroad car or truck, they use 30 degrees most of the time. If they ran zero on the arms the impact from the jump wouldn't compress the shocks. Castor at the wheel (castor block) is for tire contact patch while turning. Hope that helps

Valentine is correct - kickup and caster are two entirely different things, and did a great job of explaining the difference. If you have any additional questions, feel free to contact me at the shop M-F, 9-5 EST...:thumbsup:
