    There's probably nothing stock that will be a direct fit. FWD cars use a completely different setup and trucks generally have different parts too. There's no real benefit to changing what's already there.

    The parts already exist. Contact Bill Harper (Navy Lifer) over on the Impala SS Forum. TCE also offer custom hubs that will accept slip on rotors in sizes from stock to huge.

    Sounds like a step backwords, the old style never warp, the floating rotors warp when you put them on.

    A 15x1.25" rotor does not warp. A slip on rotor on a Civic does, though!

    Rotors don't warp, period. Ask any brake manufacturer.

    What do you mean? I've personally turned warped rotors. Two feet drivers for example...

    Pretty sure that was facetious.

    You've turned rotors with uneven wear side to side. Rotors don't actually "warp" (change shape) into an untrue state.

    I was wondering also why anyone would want to do this in the first place.

    Resisted the idea uneven lug nut torque would lead to wacked rotors and lumpy brakes for a while. Finally I learned this was true.

    Bigger bearing, less weight, more rotor options, different bolt pattern... The reasons are there for the more extreme conditions but, for daily driving, it'd be tough to justify the move.

    Moist, your reply makes sense but I think most people will call uneven wear the same as warped. Either way, the rotors would need to be turned.

    Yes, warped is the commonly used term, just misleading.
