What about a standard M3? The ZCP package is nice, but in all honesty, The standard M has limitations are higher then I could ever push.

ZCP

- 13.6 brakes in fron instead of 12.7, Rears are the same size. (this is also an upgrade you can do yourself later, if you want)

- 14.5 steering radius to 15.4.

- Slightly stiffer suspension. But from what Ive read 05 and up got the same suspension as the ZCP. Not sure where it comes from, but Im guessing the bushings and shocks. Coilovers put both back on a level playing field.

Im pretty happy with my braking and handling as it is. Only thing I will probably do is swap to a better brake pad and upgrade my RTAB/FCABs.

You could save a few Gs that way. ZCP is usually about 3-5k more.
