i'm pretty much set on getting jwt flywheel and clutch, partly due to quality and partly due to cheap deals buying both together.
i do like changing gear so would probably give the final drive a go depending on price. can you let me know if you get any decent quotes? maybe cheaper to buy in bulk? i'm a bit wary of remapping the ecu for more revs, as there's always a reason why you don't get them with stock. . .
anyway, just out of interest, below is stolen from 350z-tech

not convinced the z would do 185 mph so there is some wasted gear ratio going there. . .
