What is the best Front Roll Center location for DIRT
Been to some other forums...and read many books, and everyone seems to have a diffrent take on where the roll center should be on a DIRT car. I'm thinking the RF camber gain/upper a-arm angle would be more important than actual "static".
I'm actually building a new Late Model Sportsman (with a camaro stock front clip, stock lowers and spindles). Got it up on blocks and I've got 17 degrees on the uppers... 1-3 degrees on the lowers (LF has more than RF). The roll center draws out to 5 1/4" off the ground, and 4" to the right. My upper mounts are serated, so I can move the RC left to Right fairly easily. I have 2.5 degrees of camber gain in the first 2" of travel.
I would love to hear everyone's opinion on this, and also try to see what seems to be the norm for some of these LM chassis builders (what seems to work for them)
