I have about 8700 miles on the car now and the tranny is fine (so far). 5. The car is closer to 500 rwhp after the last Z1 tune. 6. I race locally quite a bit, so the car is being pushed.

All this being said, the car is a beast and has not been beaten yet. Someone said something about a Z06 and I will say I have not raced one yet. I will add that the race will be closer than you might think and my money (and probably Johns) would be on the Z winning. John will tell you that I am a modest guy, not a junk talker. Until you actually ride in THIS car, you have no idea how it feels and runs.

BTW, even considering all the challenges of this install......I would still choose the 7AT over the 6MT for the TT. Not hating....just saying.
