The Stock C5 Caliper Bracket is attached to the Adapter.....not the stardard location on the wheel Hub Assembly. The C4 Caliper Bracket is different I am sure but have to check. It is C5 Caliper Brackets I am using in this conversion.
The WIlwood Rotors are 12.8 inches diameter but the Hat is selectable......making the Wilwood Rotors different than a stock C4 Rotor regarding Offset.
A stock C4 Rotor is 12.8 inches diameter and the offset is 1-1/8 inch.
My Wilwood Rotors with Hats have an offset of 1/2 inch. This particular Offset works perfectly with the C4 to C5 Brake Adapters you find on Ebay as long as they have the recessed area for the Caliper Bracket Connection to the Adapter. I received a set of adapters from
FlynBye that did not have the recess and they would not work.
With that greater Offset using stock Rotors the Caliper is significantly further away from the spokes
than my C5 Z06 Calipers which have 1/4 inch clearance to the spokes.
