Reply to "What is involved with changing to outside hats?"

Why do people think they need instant access to the rear brake rotors by mounting them outside the axle flange? Maybe for pro-racing.... It complicates caliper mounting, e-brake positioning and requires longer brake flex hoses, cables etc. The only street advantage I see is, the wheel studs cut their anti-rotation splines in the steel axle flange instead of the aluminum hat-flange.

Along with David Nunn's comments, also consider that some of the current aftermarket outer stub axles seem to have stronger, thicker flanges. And since the stub axles were designed as a drop-in replacement for stock hollow axles, any extra flange thickness may be toward the outside so stock rotors mount at the stock position inside. It's maybe only a little extra but it seems we're pushing the unflared stock body limits with 10" Campys and 295-50s x 15" already.
