For any RS owner, the rear tie bar is a good investment. hey for $45 and a 15 min install with simple hand tools, why not.... I've noticed major decrease in rear end sway, tighter turning radius, the car just feels more solid. I currently still have stock suspension,stock wheels, rear GST sway bar, OBX upper tie bars.
Just waiting for the weather to warm up,so I can install my newlt delivered rm sway bars. :D

One question tho... for you handling fanatics .....
Would it make any more difference if another lower tie bar was installed on the other side of the LCA's???
