Yea 4.0 ring and pinion swap from the stock 3.5. I am not to worried about that to much though. I know that the nismo gears are a good mod for a n/a car, 15% accel increase in every gear with very minimal top speed loss(Not like I will reach the top speed on a 1/4 track or autocross anyways).

I am more worried about the clutch/flywheel and suspension parts. Like I said..all these parts come highly recommended from other forums..just want an outsiders opinion if you get what I am saying.
