?? on springs
 

FRPP overs 2 sets of springs for late model stangs. Only difference is the rate on the front springs.. one is 425/530 and the other is 650. Was wondering wich application i should go with for my 1992 GT.

What are you going to be using the car for? If its a daily driver, go with the regular (425/530) springs, they will give a lot nicer ride. I don't have any comparison experience, but the 650s are specific rate (650, all the time) and obviously a lot stiffer. The others are progressive, and start out on 425, then progress to 530. Little loss in performance, but much better ride.
