Question for Brake conversion Gurus, Do these look right? Options

[skline]

I am in the process of installing a 1971 911 front suspension. I think its a 71, anyway, I put all new bushings, bearings, brake lines, rotors, and I am using Volvo 240 brakes witht he 3 inch spacing with spacers behind them to correctly position it on the rotor. It bolts right up and I am sure it will work but my question is, it doesnt look like it sits down on the rotor like it should. The factory calipers that came with everything are the M calipers and they dont even fit over the rotor. Am I missing something here? Were the rotors for earlier cars thinner? These were for a later model car I think. I had them cross drilled. But I ordered factory vented rotors and this is what I got. How come the factory M Calipers dont fit over them? Or am I making a mountain out of a molehill? I want to be able to stop. Help!

Sounds like you got "Carrera" rotors. M-Calipers should slip right on a standard vented rotor, drilled or not.

Another question; what calipers are you using on the rear?

If you're staying with stock 914 calipers then I'd match them up with the M-calipers and some "awesome" pads. If you plan to go larger then by all means modify your existing calipers to fit in closer to the hub.

In choosing a rear caliper (if you're going that route) I'd check the overall pad area on the Vulva pads and match them up with a Porsche equivilant and then use what Porsche used opposit that. E.G. If it's the same pad area as a 944 Turbo then find out what caliper they used there and make it work.

Drop the proportioning valve in favor of the "T" fitting or go the adjustable route.

Larger rears also mean parking brake issues... it does end at some point.
