Im looking for the Red Z owner in Cambridge with the Gunmetal Volks (GTSs??). I''m finally doing my 4.08 FD but not sure if it's really worth swapping out the VLSD for the Quaife. Was hoping to get the owner's insight, possibly a ride. Please get intouch with me, it would be greatly appreciated.

 

Hey I think you mean me? Ran into you at the Shell on Franklin?
Black Volks tho.

The Quaife is expensive if you're not going to be tracking the car, unless you bought it already in that case just install it.
Clutch diffs are cheaper but require frequent oil changes, and are noisy at times.
Does a diff make a difference in performance? Yes, when you are hammering thru the corners, accel/deceleration.
The gears will make a nice difference either way so no worries, but if your not going to track the car then I'd save the money on the diff. Maybe get a Nismo diff cover and some Whiteline diff bushings.
