Ditto. Tires make a huge difference. Take a look at subframe collars/or bushings, they help stiffen up the rear quite a bit. How is the 180sx sway bar working for you?

Other than that, seems like you have a good starting point w/ the exception of tires.nismofly wrote:the absolute first thing is better tires, since youre already going to be in a higher class take advantage of it
