Coupe of questions about brakes. First of all what is the difference between "M", "A", and "S" capliers? Is it the mounting bolt distance? Early vs.Late? (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)
Did the 914/6 come with "M" capliers? If not what did they come with? Can these brakes be upgraded to something like the "big reds? |

We discussed (Mike Mueller and others in a previous thread) machinging the -4 but I'm afraid it's out of the question. You could take the bore out but you'd have no lip to attach the boot to and I'd be "very concerned" about the stability. Then there's pistons in general and that pesky inner piston assembly. 38mm pistons, or any part on these calipers for that matter, are unavailable. I suppose you could machine a new piston that would take the innerds of the -4 but... monumental task.
I don't think the V-Caliper would help much other than to situate it on a vented rotor. A V-Caliper, T-Fitting and an agressive pad would probably be enough to keep an A or S-Caliper happy but that's about where it would end. Jim, an M-Caliper is an M-Caliper with or without the spacer. So... if it looks like the one with the spacer that you have on Ida, then it's an "early" 911 M-Caliper. Especially if it has a hub and a detachable rotor vs. a 914 rotor/hub. If it's fluid hole is on the bottom it's a Beemer. |
