do you have integra rear LCAs? You'll need either those or ex sedan LCAs and endlink hardware in order for the swaybar to bolt up. I'd say go for it, it'll definitley make a difference. The gs-r bar is 19mm, I believe, but I'm not sure on that. When you decide to upgrade, I'd go with an adjustable like the Skunk2 22mm rear sway over the ITR... just to help fine-tune your suspension. I think with your setup, you'll want all the adjustability you can get.
