The car is loose,add more cross weight and try a softer LR shock.You might also try a 2" offset on the RT front.Check for suspension binding and shock travel.If you can move the rear springs,put the lf rear forward and rt rear on top or behind axle.

300 on the LR and 175 RR springs is a bit much of a split. Try a 250 or 225 on the LR. That'll let the rear squat a bit more evenly. Right now it's transferring all the weight to the right.

Are you running any stagger? That will loosen you up and heat that RR.

i have to agree with raz......that's an awfully soft spring on the RR for a 3400 lb. car.

I like the springs-I'd like to see more left static weight. Move some of that "unseen ballast" over to the left side.

Shoulds like the car is loose as well you may want increase your left side weight. This will get more heat in the LR. If you have your fuel cell or ballast mounted high in the chassis you may be rolling alot of weight into the RR.

Also keep in mind that you can only hold your hand (continuously) on something if it is less than 130F. So you should invest (or borrow) a pyrometer. And depending on your tires even 200F might be okay.

I'm having the same problem. Will the left side weight increase if a stiffer RF spring is installed or can you only increase left side % by adding ballest?

Could the springs be to weak for a 3600/3700 lb. car? Ya, the car is a 76 Monte It handles ok, just seems to roll to much and not enough bite off, RR HOT! Sorry no scale readings. Always run 2" on RF and sometimes on LR also, with white spokes on the others. Bilstien street stock shocks, G-60 AR tires.

LF / 1000 RF / 1250

LR / 250 RR / 225

We have tried lower air pressures, but any thing less than 18 psi in the RR and it rolls off the rim. On a rough track we have pulled off the RR with 22 psi.

These are 60 series DOT radials, and everything I have read on radials have lead me to belive they don't benefit from the lower air pressures the way bias-ply racing tires do.
