In the process of converting to 5 lug and also rear vented rotors, there appears to be two ways to go about it. Both have been explored and written about by Eric Shea over the years. (Ya, I've done a lot of searching and reading)
One is the usage of a late model 914 rear caliper with spacers placed in the body, to get the needed clearance for the vented rotor. (as I read it; a late model ATE caliper is used and not a rare 914/6 caliper) A spacer is required between the brake rotor and hub (moving the rotor and wheel outward). The rotor (911SC) has to have it's diameter shaved down 4mm) The parking brake cable just hooks up as stock. The other option is to use the "M" caliper from a 911 and also the parking brake assembly. Mounting the parking brake assembly requires grinding and welding on the housing. Hooking up the parking brake cable requires fabrication, but is possible (and can be found by searching this site). Now I can think of plus and minus points for both, but I'd like to hear from others. Wes Vann |

I feel the Carrera rotors are heavy and overkill for this application. The Carrera axle shafts will be about 19mm short unless you are using PMS adapters. Also 14mm spacers are huge and require about $3,713.00 worth of custom 12.9 fasteners (rough guess) (IMG:style_emoticons/default/biggrin.gif)
The simple advantage to a V-Caliper is, it allows you to use a (milled) 911 vented rear rotor on your car without any custom handbrake solutions. These solutions can get expensive quick. With a V-Caliper or a V-kit you'll be in it for the calipers/kit and the cost of the rotors. You use your very same handbrake cables and bolt them up. Your rear rotors should last quite a long time in this configuration as well. I don't know of any flex issues with these. Rear M-Calipers have the 10mm spacers, rear Carrera calipers have 14mm spacers. From M-Calipers have 7mm spacers... Basically, this is probably the cleanest and most cost effective ways to add a vented rotor. |
