IRS camber for autocross
 

I have upgraded my Factory Five roadster to the FFR IRS based on 2015 Mustang bits. My question is what camber to run w/ 315 A7s for autocross. My only reference is a well known FFR track racer who runs in the high 2s front and rear. I am thinking though, that at autocross speeds w/ my 351 based 408, that I could lose straight line traction more then the road course car would. I have been running -3 in the front for a couple of years w/ good results and tire temps. Thoughts guys?

Just FYI, I was recently on the Corvette Forum and there were several posts on rear alignment specs to include autocross, track and street.

This is sort of like asking "how hot should my coffee be ?".

No one can tell you what camber your car needs. And on different tracks, different days, the most effective camber will be different. Not to mention tires and driving style. Nor do I know what the camber gain curve is on that system at your ride height. So what you are really asking is "what is a good baseline camber number to start with ?"

My suggestion is to start with 1-1.5, and then take tire temps and adjust accordingly.

I understand. Your last sentence is what I am looking for. I figured some numbers that others use that are working would get me in the ball park sooner.
Thanks.
