Thanks for the quick replies guys. Should I expect about a 5% increase in power to the wheels due to the decreased weight and vibration in the drivetrain? The reason I ask is that a friend of mine had ordered one for his R32, but was sent the wrong one, which will fit my R34. So I'm trying to decide if I want it. My car is mostly stock besides an uprated nismo intercooler, hks downpipe and exhaust, nismo intake, hks suction kit and ORC twin plate clutch.
