I want M Coupe or E36 M3 rear brakes on the E30. I'm going to finally be able to finish the S52 swap at the end of next month (barring any major problems). In the winter, I want to go 5 lug. I want to use E36 M3 stuff up front (so I can use the Euro floating rotors), but the Ti stuff out back would not be a good combination, I believe. I'd like to have the brakes off the car that the engine came from. Considering the E30 is lighter it should be a NICE upgrade while avoiding the expense of expensive rotor/pads replacements of a BBK. I know the E30 M3 guys use a rotor spacer to use the E36 M3 stuff, but thus far, it seems no one has figure out how to get E36 M3 or M Coupe brakes on the back on an E30 without swapping on the M trailing arms, which are not only very difficult to find, but expensive as all get out when you do. Any ideas? I have some car enthusiast buddies with ME degrees and I think we might see if we can work this out, but wanted to see if anyone else had some ideas.
