Ken you can take a lot off those calip. I never thought to cut the rotors cause if i had a come back i would have to make another rotor. But i dont see why you cant.The only problem with that is you will have to remove some of the brake pad cause the inside will rub on the radius.(and maybe some of the calip) The vette calip fit good plus it stopped real good. Yo do have to make a fixed braket as it is not a sliding calip.Its 4 spot also.How about welding the wheel and grinding off the rivets?????Gotta be safer than rivets.
