Mines had no problems whats so ever, I'm over 600 at wheels and not afraid to drive it a cross the state at anytime. It's been very reliable. It honestly depends how u drive it. My stock clutch lasted awhile before it acted up but at my power level it was only a matter of time. Plus mine only saw the 1/4 mile a couple times. I do drive my car hard, but not on sticky tires, I run 315 nitto invos and I believe they stick less than the Pzero it comes with.
