Yes they are a few methods to improve braking on the E28 M5. The first is to put discs from a 750 iL at the front. They have a much better cooling pattern. They also are thinner (2mm), so beware with worn pads.
There is another way to improve braking, and this is to put the rear discs and calipers from the E34 540i at the rear. It highly inproves rear braking, modifies the bias somewhat and eases the task of the front brakes.

PS, you must be lucky to own this car.I can't find a suitable one here in Switzerland...
Does Anyone know if there is a straight forward conversion for front brakes on E28, 1988 M5? I have heard that the 850 CSI front brake are a straight bolt on application. Any help is appreciated!
I agree the E34 540 rotors and calipers will make a huge difference for street use. I upgraded to this format a few years ago when I was using the car as a daily driver. You may not even need to upgrade the calipers, since the 540 rotors alone make a good bit of difference. For the past two years I have used the car as a track racer and I now have Movit Porsche GT2 brakes on the car. They are unbelievable but also very expensive, but unlike most of the "pure" racing brakes from Alcorn and the other types don't need to be rebuilt every so often and the Movit brakes require little or no maintenance during the course of the year.
especially the US guys can use brakes from chevy(corvette) the bolt pattern is the same as bmw, only thing to do is make the center hole of the disc ok for the bmw axle and weld a connection for the caliper !
i did it a few years ago the other way, i putted brakes from a 528 on a chevy impalaSS from 1965, it works perfect .
Thanks a thousand times, Raymond.
It's the exact reason I take part in these forums, people helping each other.
I called for the car, it seems interesting.

Tom,
I have no idea. The only M5 E28 I saw only had the front brake conversion.
For the rear, I would check if the disc dimensions match (diameter, thickness parking drum). BUT, The main point was to increase clamping force, so putting better discs will not increase that part of the equation, as thermal restrictions do not seem to be the problem in that case.
Hope this helps, George

George,
Thank you for your response. I have replaced the front rotors with the 750i rotors and have had no warpage yet! Do you know if the E34 540i rear rotors and pads will work with my existing calipers? This would obviously be a very simple and straightforward improvement. Any info would be greatly appreciated.
