My front end is the stiffest (1 inch sway bar, 620# 1 inch lowering sprigs, KYB Gas a just, poly bushings, refurbished everything, etc) but my rear end feels loose and rolls more than the front does. So I was looking at a sway bar primarily to help with overall stability of the rear end and to aid with handling. Now, my rear end is not worn out or anything, the leafs are in great shape, just changed out the bushings for the leafs for polys, the car has subframe connectors and KYB gas a just in the rear as well, and the rear has been lowered 1 inch. I dont drive the car in autocross or drag racing but I do like to have some fun with it and it sees some canyons by the beach. I am just trying to get the record straight on rear bars unless there really isn't a definite answer lol.
