A guy at work is selling the Wilwood BBK from his 2013 C6 Corvette Grand Sport. Wildwood Aerolite 6R Calipers, Bracket, Brake Pad kit with Front Promatrix 14 inch diameter vented two piece rotors and Wilwood SS brake lines. Has anyone fit this large of a rotor on the E-body? I've got a 73 Cuda with OE disks on the front. I went on the Wilwood site and only kits I could find using this 6R caliper require Magnum Force 2" drop spindles but only with their 12.88" rotors. Was hoping that someone has paved the way using standard spindles. I don't know why they don't list the bigger rotor but will call and try to find out. Seems like it should just require a different mounting bracket as long as the offset in the rotor is compatible? Was hoping I could pick up his kit "cheap" and then either Wilwood or Dr Diff hubs and then address the mounting bracket. Am I missing anything? Are these calipers essentially the same as Brembos from a mounting perspective?
