xavier:
Before i swapped my RC33 (3.357) diff to the RC36 (3.692); I installed a Quaife QDF10L,,,which was the only traction device at the time for the factory 3.357 A/T diff.
It performed really well & would bite hard when tires were hot...Though i was told that if one rear wheel was lifted-the raised wheel would spin only.
The Wavetrac helical lsd is supposed to be a step above the Quaife...Just wasn't available for the 3.357 gear'd diff at the time.
I got the Nismo diff RC36 (3.692) & only removed rear cover/flushed & installed new oil & bushings.
I never counted toner ring teeth; as these work the speedometer as well as abs...all worked great. Just with cruise control on, ecu would get confused as the rpm's neared 3k & Z wasn't running 90mph (like factory)....as long as i stayed below 75 or so...cruise was fine.
rev match,up-shift,down shift was perfect & speedometer was dead on with 27" tall rear rubber.
I'll add a few pics....But performance was enhanced w/gear swap.
