Quaife LSD in 7AT
 

The good folks at AAM COMPETITION performed the installation of the Quaife LSD on my Z.

Mine is a 2009 Touring (no-sport package). The opinion I'm giving is based on going from a car with an open diff to the Quaife LSD. I can't comment on going from the sport model equipped VLSD to the Quaife LSD.

Onto the good stuff. The difference is tremendous. If I had to put it into words I would call it "confidence inspiring" and it really allows me to enjoy the car even more. I will state without doubt this would be first modification out of the bunch if I had it to do over again.

I would also always drive with the VDC on. Now, thats only be on during the rain or snow. To give you an idea of how bad I felt about keeping traction I would purposely avoid being lined up first at a red light against cars even significantly slower than the Z simply because it was so damn difficult to get on the throttle hard with that open diff. Sure part of that is me but thats how much bad I thought about it to avoid being the 1st car sitting at the red light. None of that matters anymore, it was 38 degrees out nobody was out on the road with me so I got to try several very hard road launches, I was jumping on the throttle about 75% and just holding it there for about half a sec and then stomping it and hitting second gear. did this severals times, felt like grip had improved by 300% seriously. Could barely feel either tire lose any grip at all. even when it does start to slip it's like the grip comes back almost instantly. I can't tell you how different it is from the open diff start to slip, you could feel the tire inside the car just flopping or whatever, just made you sad. that crap is gone thankfully, this thing hooks up and rolls now. I am going to try just stomping on it from a dead stop to see how that reacts but I image that should break it loose but it'll be fun :driving:

as for sound I can't even tell it's there. there is no clunking/clanking and driving around slow in heavy traffic or accelerating hard or highway driving no noticeable difference in sound that I can detect.

Haven't really done any hard acceleration coming out of corners yet but just from the few exits I've zipped around with moderate throttle, still no different noises but something does feel a bit different, I honestly don't know what it is and it feels good like the car weighing more on the outside tire or something to that effect, it's weird, it feels great I just can't put my finger on exactly what is different in the corners but getting on and off the throttle during the corner feels steady and confident. Like I said though I wasn't trying to hammer around any of the exits at this point.

so, to me at least, this is worth every penny.I imagine I can still light em up if I really wanted to smash the throttle from a dead stop and maybe once in awhile yeah. This traction thing though, awesome.

Confirmed, VDC off, you wanna stomp and slide that works perfectly fine. guess you do doughnuts to your hearts content as well. Didn't try with the VDC on. anyway point being you can still slide it all over the place if you really want to.

Well, the million dollar question is, "Is it easier to CONTROL your slides?"
That and getting a more solid hookup at launch is what the LSD should really do

I'm not one that goes sliding or drifting around corners so I have no idea seriously. It's easier control in a straight line obviously because the car isn't yanking to the left so in that respect yes.

yeah the launching is definately easier. I guess we'll find out via the 60ft time at the track. my helmet should be arriving tuesday so I should be set for this weekend and for future HPDE events that I plan on going too.

course I did buy a samsung galaxy tablet 10.1 yesterday so I guess spending money on something other than the car is a 1st outside of regular bills.

Did this come with everything necessary to install on the 7at?

Yes and no

For Kevin's install, we renewed the diff carrier bearings, and seals with OEM Nissan parts roughly ~$130, and of course fresh diff fluid. Could we have reused all of the above, well sure, but after dropping $1300+ on the LSD, I'd go the extra step to take extra good care of it!

Even at such low mileage, I think Kevin's around 22k? That diff fluid was not pretty!

I was already planning to do this as my first mod before I even bought the car! :)

Glad to see a review. Instills a little confidence that I'm approaching this from the right direction. Thanks!

OP Can you post a link to where you bought the LSD from and how much and what version/model?

Thanks

Z1 sells it at 1,100, i think

thanks

I have a nice system I use. I call Khoi, tell him what I'd like to do, he tells me ballpark price sends me a quote on parts n labor. I swing buy drop of payment, they order everything needed and install. Me happy, and do nothing except pay.
