hello,
I am currently upgrading my 914-6 to vented rotors. My hope was to take a Front "M" caliper and mount it on the rear using the 911 (69-83 Rear) vented rotors. I mock fitted the caliper and rotor and it looks like I need to place a small spacer between the caliper and the mount on the rear trailing arm (not a problem) The issue is the 911 rotors get larger as you get closer to the brake surface and rub on the "M" Calipers. Has anyone else had this issue? I realize they are larger for the parking brake, is there a parking brake delete option? 914-6GT vented rotors, suppliers? Thanks for any help, back to the drawing board! Steve |

Brake Update Pictures of the front and rears, thanks for all your advice. Wide A calipers in the front, M calipers in the rear (38mm), with T installed and adjustable proportioning valve.
