While ZCP is a "hot option", in actual function I've found the non-zcp (regular shocks) M3 to be superb. I was actually specifically hunting for a non-zcp back in 2012 since the 19" autocross (stock class) tire selection didn't exist then; then the SCCA changed the rules to allow +/- 1" in diameter specifically for this reason, and the ZCP became desirable for it's additional 1/2" wheel widths and everyone uses 18" aftermarket wheels now on ZCP cars.
Anyway, if you're going to put decent shocks on the car anyway and/or modify the suspension, ZCP isn't worth fretting over imo.
My most important concern was finding a slicktop since I can't fit in an E90 with a sunroof and helmet on (in addition to actually never using a sunroof anyway plus the bonus of not having 30+ lbs of excess weight sitting at the highest point on the car).
I've never understood why BMW chose heavy cast wheels for the ZCP package either since the 220M are forged, strong and light, comparatively. I have a set of ARC8 10" wheels that resemble the ZCP but are wider and lighter -- use them for time trial type events.

), change the gear close to the red line.
