I have a 914-6 six with stock size front rotors and four piston Brake Tec calipers. Does anyone know of a larger diameter rotor that will fit these calipers and still fit inside a 16" wheel? You can email me at thannum@cox.net Thank you for any help.

Here's a set of custom hats for coleman rotors - I'd be the sky is the limit on rotor choices at that point. Cheap too.

I have a 914-6 six with stock size front rotors and four piston Brake Tec calipers. Does anyone know of a larger diameter rotor that will fit these calipers and still fit inside a 16" wheel? You can email me at thannum@cox.net Thank you for any help. stock diameter should be 11" , the next common diameter is 12.19", so can you remove a wheel, and measure to see if you have .595" of space between the OD of the current rotor and the caliper?? I kinda doubt you'd have that much room, but who knows.... if no room, your next option would be to space the caliper to clear a larger diameter rotor, or depending on the caliper, split the caliper, add a spacer and run "wider" rotors (this what the factory did more or less for the '85 and newer 911's, same OD, but thicker rotor which will absorb more heat) As for those those adapters on Pelican, they look pretty darn used and they are a consumable if abused too much. FYI, 12.19" diameter rotors won't fit unless you change the offset of the rotor towards the outside of the vehicle, if you bolt a rotor that large to your stock hubs, it will hit the a-arm. Below is a setup I put together using Wilwood parts. In order to fit the rotor (so it does not hit the a-arm, it needs to be flipped around (looks odd, but Wilwood does it on thier Mitsubishi EVO or Suby STi big brake kits)...TimT mentioned that you can also move the entire hub outboard by about .25" if you have a spacer behind the inboard wheel bearing. These will be going up for sale pretty soon, probebly going to ask $200 for the hats, 2 new rotors and the bolts that attach the rotor to the hats. Replacment rotors are $37 each (IMG:http://www.914world.com/bbs2/uploads/post-2-1110991891.jpg) |

Mike, nice setup. Do you have the part numbers for the Wilwood stuff?

Mueller what are the width and diameter of that rotor? Were you happy with the performance? What did you run on the rear of the car? Any balance issues? Did you use a adjustable pressure regulator? What size master cylinder? Thanks

What size master cylinder? Thanks 12.19" x .810" sold the car to which these were supposed to go onto....they are just collecting dust in my tool box (IMG:style_emoticons/default/sad.gif) originally Mazda RX7 Turbo calipers had been planned to be used with them and I would have tackled the other issues as I got to them. Only real differance between these rotors and pre-84 911 rotors (besides being lighter) is the OD is a little over an inch larger on these |
