what happens if you race alot with a new 350z and reached near redlines alot before the 350z even reach 500 miles???
cause i did....and im retarded....and i think my car is goin to hell now???

couple people said it was ok...as long as i dont do it no more...
but im still scared...

 

Don't worry about it, sounds like you won't have it any longer than the 5 year 60K mile drive train warranty. The next owner is the one that needs to worry.
