In for the update! BTW, did you look at the Wavetrac diff? Why did you go with the Quaife?

I started looking at different diffs but the Quaife kept coming up, I've mainly heard and read good things about it. I still wasn't quite sure so I asked the manager Mike Hanson @ Whitehead performance in Vaughn Ontario where I get most of my work done .
Here's parts of the email he sent me.

" I'm not sure about the
Quaife diff.
In your professional opinion, is the Quaife diff worth it?
The better question would be .... Would you put the Quaife diff I your own car ?"

He answered this " Yes every single time I have the chance to install a Quaife I would. Especially with 4.08 gears because the tires so in easier with these gears. The vdc is a lot more active with the stock viscous lsd. Having the Quaife reduces wheel spin and vdc intervention improving acceleration. Same holds true with vdc off.
Finned Diff cover for better cooling and urethane diff bushings for less diff movement under acceleration are two items we commonly do with a diff upgrade."

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

Where did you buy the diff & gears from ? I'm looking to buy the same diff right now & tryna piece everything I need together . I have a 2012 base model which I think comes with the open diff or (peg leg diff) & looking to upgrade

Its so hard living 5 minutes from their store, Every 2 weeks when I get my paycheck, I walk their showroom and look for "Something" to buy. I got a tour of the garage area a few times and there ALWAYS seems to be a car or 2 getting a turbo kit installed and im caught staring at an engine bay for 20minutes. 1 thing is for sure, Z1's install quality IS 1000% SECOND TO NONE. you are FOR SURE going to get your car back cleaner then it was when it was brought in! Looking under neath when they have cars up on a lift, all wires are tucked and zip tied etc.... I never think twice having them do ANYTHING!

newls96,,,You should get a valuable coupon for that comment.
Good Advertising,,,I enjoy speaking with the knowledgable staff & have purchased some parts there; I haven't had any parts installed-but Jon did dyno-tune my car...I hear that they are very competent at installation/engine building!
