Finally installed my Diff
Well this has been a busy year for me, and my Quaife that I purchased from Z1 has been sitting in my parent's garage for over 1/2 a year. Yesterday I FINALLY installed it.
The differential is a Quaife built by Z1. I had them install the differential with all new internals.
This was a job that I wanted to do from start to finish, but after much research, I figured I would let the professionals at least put the pumpkin together.
Saturday I removed the cover, installed the Z1 extended diff cover and Whiteline bushings, and Sunday I went at it with a buddy of mine.
The only real issue we had was removing the rear diff bushing, as expected. I used the Z1 remover, which removed the bushing fairly easy and quickly. When it came to removing the sleeve, I got it about 1/4 out with the tool then said screw it and cut it out with a dremel.
From start to finish, the job was about 7 hours, which included a lot of breaks. The biggest problem we had was working underneath the car with just using jack stands. Last time I changed my diff it took maybe 4 hours, but that was with a lift and I didn't change the rear bushing.
Now onto the fun stuff. How much better is this differential? Holy crap.
This took so long to go in because I have been toying around the idea of getting a new car, as my love for my Z has dwindled as of late. Let's just say that the Quaife has renewed my love for this car.
I want it to break in more before I really get on it, but the way I can put the power down around turns and the way the solid bushings feel, this thing is amazing.
I highly recommend this upgrade to anybody that has this car. I have been through the stock open diff, VLSD, and now Quaife, and the difference between the VLSD and Quaife is much more substantial than the open diff to the VLSD.

So rent me that bushing tool? I've been debating clutch or diff since both "work"
But after yesterday tracking with some beat tires. Then VLSD openness is even more evident as I'm spinning a single tire around every turn and can not put down the power for ****. I need to make this purchase but it's more then I make in a month lol
I'm a young parent so I don't have the income most this site has. Guess it'll have to wait
Really want a used one to pop a up already

It took me a while to finally pull the trigger, but it is by far my favorite mod yet.
Yea I know, but I still felt the need to put some miles on it before putting a beating on it.
Went for a ride last night and had a little fun. Boy this thing is awesome! My favorite part the how predictable it is. The way it grips is amazing. Finally my Michelin Pilot Super Sports are getting used properly.
Nothing but amazing experience with Z1 on all my purchases with them.
this is not including shipping and tax yet...
were prices raised?
I'm pretty mechanically inclined...does anyone know if it's easy to self assemble and clean everything like it's brand new?
if you are comfortable doing it, just buy the diff itself.
here is a good write up that a buddy of mine did, and if i am correct this is the diff that was in my car
