I have the Stage 3, you still have two conical bearings in the hub hat just like stock. The caliper is identical to the PBR used in the 94-04 Cobras and others. The rotor is not 13" Cobra as i understand. Its a great kit for the price. I had a Baer 12" setup on my 92' GT and the caliper its identical.
Why a 17" rim when you can fit a 15" if you going to run a skinny tire?
I ended up ordering custom offset rims front and rear to get what I wanted.
