Update
I haven't had time to track it yet but WOW !!!
The Quaife & Gears have been in for close to 3 months now (happy happy happy)
The car now pulls throughout the whole gear in every gear !
The Quaife is amazing, way less tire spin also I can do a lot more " spirited" driving with the traction control on because the LSD is way less intrusive.
I pull away with ease on Stock Mustang GT's and Camaro SS , there's 2 GT's in particular with full B/O's that I'd like to tangle with but haven't had a chance too yet , I'll have to set something up at the test and tune down at the track one night.
Out of all my mods the rear diff ones are the ones that gave my Z the most gains and if I'd have to start my build over I'd do the rear diff first!!!
The only negative things I have to say are ....
Gas mileage went for a **** ...... who cares , I didn't buy this car for gas mileage
Revmatch is off by 100-200 rpm , its no big deal ( if you heal toe) , I'll see if if my tuner can fix that
