This car has always had fron bias - in fact both of my cars have. The car is an '88 and the old one was '86. Maybe an '83 is different?

The ride height is set to 5 inches at the rear and 5-1/4" at teh front, so there is ride-height bias to the back. It's a little more on the right...

BTW had a good race at Road Atlanta last weekend. Finshed 3rd out of 12 cars from a 7th place start. The handling was excellent save a little too much understeer. I like the new R6 tires (new for me anyway).
