I've seen reviews from people that have tracked both and found the difference to be negligible. Not saying you're wrong (it is an opinion after all), just saying that thinking ZCP makes much difference on track is an unusual opinion to hold.

OP: Definitely will be 'good enough.' I like coilovers much better than stock, but even non-ZCP stock is pretty damn good for a stock car. If you were happy with an older M with stock dampers you'll love the E9X.

My tire wear has been terrible stock and with coilovers and 2.5 camber.
Agree. I don't see how there could be such a big difference. These aren't coilovers by any stretch. Lots of subjective interpretation in this thread. also apples to oranges, comparing stock vs modified square setups vs Dinans, EDC vs non-EDC vs ZCP, butt dynos vs track tire wear...

OP is talking about running his car stock for now.

Feels extremely neutral coming off an off-ramp at relatively high speed (track of course is different).

Thanks for the thoughts though, looking forward to seeing the ZCP suspension in action this March.
Springs are shorter by 1 cm (0.4") and spring rate is same as non-ZCP = not stiffer.

I think the ZCP has stiffer rear springs and stiffer damper settings which helps to mask the problem.
Wrong

Totally agree.
