Autocrossing my 03 sedan and would like to firm up the suspension some.
Has anybody put aftermarket sway bars on their G?
Any suggestions?

 

350evo bars.

 

lots of discussion on this one. i have Hotchkis, but in retrospect, i HIGHLY recomment Stillen sway bars (www.stillen.com). here's an excellent summary thread for you:

EVO350, Stillen with Prothane bushings, or Hotchkis with collars added. What to get depends on price point, and how much bar stiffness you need (since I don't know what class rules you may be bound by). Of course all you need to change at the limit behavior is the ability to adjust, hence no need to chase stiffness by the numbers.

Are you bound by class rules that prevent you from running a aftermarket rear bar by chance? If so you do have front bar option from Carter Thompson and Stranoparts.
