I've got a versailles 9" in my car, and now that I'm getting more into drag racing, I've been ditching a lot of weight. That versailles rear weighs a friggin ton. I like the heavy duty housing and I have a good center section and axles, but what I'd really like to do is get rid of those ridiculously heavy brakes. I bet I could free up 40 lbs by going with a unvented rotor and a more modern style aluminum caliper. Anybody ever switched one over? I'm kinda worried I'll have to buy new axles since the rotor depth probably won't be the same.
