They are THAT GOOD. I drove the wheels off the 350z last year and I wasn't even that close to Heitkotter last year at Nats. Given that the 370z is probably far superior to the 350z, I still think the car has a huge chance though. Without having driven it, I can't comment on to wether or not I feel it could be an overdog.
So the GXP vs Z comparo: The GXP feels nearly as quick as the Z, except the Z has much longer legs and I have to shift to third on nearly any autox course (we shift to third around 52 mph, top of 2nd isn't much higher, and the car makes way more power shifting to third rather then hitting redline in second). But other then that, the GXP can nearly hang with the Z in acceleration, due to its short gearing (which is also its downfall as stated before). Now in terms of handling, it's omg, this thing is ridiculously amazing compared to the Z. First off, the GXP has fully adjustable suspension along a wide range of adjustments. (factory camber, caster, and toe adjustable). We have the front at 3 degrees negative camber iirc, turn in is crisp, steady state cornering is on par with the Z (this is the Z's strong point, put me in a sweeper in the Z and I could kill most stock cars) and the ability to get on the throttle is slightly better then the Z's. Where it really kills the 350z is initial turn in, and in quick transitions and slaloms. The Z really shows its weakness when you need to quickly change direction, etc. It's due to it not having enough negative camber, and its slightly long wheelbase. Lastly it being slightly heavier then the GXP (2960 on the scales at Wendover iirc). And lastly, the stock diff in the GXP is amazing, where as the Z is ho-hum. They aren't on the same level in terms of autox, hence the reason the Z is classed lower. No doubt in my mind, I am way faster in the Solstice.

A few of the track guys have reported killing theirs. Mine still works but I haven't had any co-drivers.

You must not be disabling it all the way, cuz every 350z I've driven that was VDC equipped, you could completely disable the VDC and TCS.
