Many have said the same thing for the E46 M3 and running a full and true rear coilover. But it has been proven otherwise for quite some time, showing that theory is rather different than reality. I know of quite a bit of guys in the E46 M3 platform running true rear coilovers and simply using a small reinforcement plate on the rear shock mounts.

I wonder if the same would ever apply to the E9X M3...
