I thought I remember seeing ATS working on a splined sway bar for camaros. I am in the market for one and right now I am leaning towards hotchkis. I know I could get a splined sway bar custom made but getting one in kit form would be much easier.
last I heard ATS was still working on it. I think they were trying to get a mandrel bender to produce them. This was a couple of weeks back, so you may want to call them or send a PM to Tyler.
