Only two members of the forum have used the reiger kit and in both case been me and Amit we only used the rear defuser. I've also never seen another Bravo with the full reiger kit in England and I go to shows and cruises all over the place most weekends.
The rest of the Reiger kit isnt too special, but the rear is better then the indy kit rear.
somewhere else there is other pics of the rest of that kit, but tthe rear and sideskirts look like the indy/carcept/carzone (whateva you wanna call it) kit
