I'm planning to trade my E90 328i to E90 M3, but I have an upgraded KW Street Comfort Coilovers. Will there be any fitment issues or anything, to prevent me from transferring it to the M3?

E9X non-M suspension will not work on an M car. I know for a fact the rear shocks won't mount up. Not sure about the front. Your best bet is to sell the coilovers and get some M-specific ones.

I second your advice:Your best bet is to sell the coilovers and get some M-specific, but not only that, consider spring rates and shock valving, the M cars are heavier.
