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.
