+1... you are crazy not to!
the rears (springs and shocks) actually are 100% interchangeable.
for the fronts, you need everything from the top mounts down to the lower control arms and knuckle. to be honest, in that light you might as well drop the entire M3 engine/trans/front subframe w/ steering rack and suspension directly out of the M3 as one unit, and move it right into the ZHP.
and definitely take the M3 rear end. besides the LSD, you also get a bigger rear sway bar and more swaybar options down the road. plus M3 rear brakes.
