Run 4.0-4.5 degrees negative on the LF and stand up the RF about 1.5 deg. negative, in the rear about 1.5 degrees negative is the best if you have adjustability on the the rear individually for camber I would try to run less than 1.5 in the RR

I run very stiff springs for an Rx-7 at Limerock, you have to watch out for the front tire contacting the unit body above the LF tire, put some white duct tape up there and look for scuffing after each session, if you are contacting raise ride height or spring rate remember to do it in the rear also unless the car has other evil qualities you are trying to get rid of.

Remember LRP is very unforgiving, creep up on the speeds you are carrying through the uphill, West bend and the downhill an off in either of those places will hurt the wallet and body.
