I have a 09 Pontiac g8 donor car. I am using the motor and tran and interior in my 67 Camaro. I want to use the G8 13 inch front rotor and calipers on the Camaro. I know I will have to do some modification to get it to work, but my question is - does anyone else make a hub for the Camaro besides Wilwood? My plan so far is to buy the Wilwood hub, which has a center bore of 3 inches and use the G8 rotors which have a center bore of 2.5. I will have to mill the center of the g8 rotor upto 3 inches unless I can find a hub that has a center bore of 2.5 inches or less. Plus the wilwood hubs are about $150 a piece. Then I will have to make a bracket for the caliper to mount.

Has anyone tried this or have experience in using similar modification?
Does anyone make hub besides Wilwood?
Any pros or cons?

Doing this will give me a 13 inch dual piston caliper brake system for less than $300 since I already have the parts available
