ZCP Suspension for Track Use - Question
Assuming you've driven one on the track, do you think the ZCP equipped cars handle well enough for several track days a year? If not, what in your opinion must be changed or if you didn't change certain aspects, why?
My initial thought is the ZCP suspension and its characteristics were built in-part to be used on the track, so upgrading shouldn't be necessary to a certain extent. I understand that camber plates should be added to improve tire wear, and something I might consider down the road. Thanks for your thoughts in advance! |

I moved from an 08 without ZCP to a 11 with ZCP and the difference between the 2 is night & day.My 11 is a lot flatter & more responsive on track with still having very livable everyday street manners.I have run my car with stock alignment settings and experienced much better tire wear than I did with my 08 thanks to less body roll.I ran a square 18 x 10 275/35 NT05 setup and the ZCP car is much more neutral than the 08 car which oversteered a lot more and got more upset when using a lot of curb.I average about 20 track days a year and run in the instructors/advanced group.

I didn't think lowering it half an inch and slightly stiffer damping would do much. I haven't driven a ZCP, but just thinking through it I don't see how it could make a significant difference.
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. |

Thanks for the thoughts though, looking forward to seeing the ZCP suspension in action this March. Last edited by Class-of-2016; 12-29-2012 at 06:41 PM.. |

I have the non-EDC with dinan stage 2, GC plates and square 275s. The BIGGEST shortcoming are the rear dampers. I can tell its on the bump stops on just about every corner exit. I'm feathering the throttled til the car is about straight and then I can give it gas. EDC cars don't seem to have this issue. I drove a stock ZCP car and it was better at putting the power down.
I think the ZCP has stiffer rear springs and stiffer damper settings which helps to mask the problem.

Thanks for all the back and forth feedback, it totally works out in my head this ZCP car will be fun on the track as-is. |

The stock suspension is plenty good on the track. I track mine on stock non-EDC dampers with just springs, camber plates and a good alignment. It's excellent.

What kind of tires? I've used Conti scrubs, RS3s and Z1* and all just didn't work very well. I'm on NT01s now and I think it will be awesome. The only weekend I used them it was wet and got 1 dry session. I could tell that the rear end had a lot more grip.

Meaning you think the NT01s feel better or give you more grip than Continental scrubs?

More grip. The scrubs I got were garbage. Its so hit and miss and then they don't last as long. So you do save on the tires but spend more time and money mounting and demounting.

But I understood the ZCP springs to be 12mm lower but NOT have a stiffer spring rate. Also, the dampers themselves are NOT any stiffer but ARE progressive in Sport mode, while non-ZCP like mine is linear, and progressive only in Normal and Comfort. Generally speaking, there will always be a setup that is better than what one is driving now. I say, learn to drive well from good instructors, move up in the run-groups, and drive the snot out of whatever setup you got. OP, enjoy the ZCP for good while, should be fun!
