what Quaife LSD does to a car is that it maximizes traction (gives double friction) and minimizes wheelspin.
It's also proven in drags which gives you a great launch, rallying and even on roads. It
eliminates torque steer and snatching in fwd cars compared to stock LSD

The Quaife LSD is 100% lock vs. 40% for pre-MY2011 and 30% for MY2012. If you buy NEW or CPO and want warranty and don't drag, then the stock ones are fine.

FYI, from their website:The Quaife Engineering Automatic Torque Biasing differential
The second mechanical method of improving traction is to use a Quaife Automatic Torque biasing differential. Rather than using clutch plates as a method of operation, the Quaife ATB uses sets of floating helical cut gear pinions that run in pockets and mesh during normal driving.
Should one of the driven wheels start to spin however, the helical gears start to generate a torque bias thanks to the axial and radial thrust of the helical gear pinions in their pockets. The result is a progressive transfer of torque away from the spinning side of the axle to the driven wheel, which is now capable of transmitting a greater proportion of torque.

Also, when you are coming out of corners, you can use more throttle, earlier on, when you have a LSD.
I think overall, it adds a lot of balance to the car and the car feels overall more stable and tied down. It's less prone to wheel hop.

No Sir, that is NOT correct. Quaife is a Gleason Torsen derivative, and as such can NEVER give 100% lock. It has what is called torque bisad transfer. And NO GT design can give 100% lock. But I will agree it IS better than the stock LSD.

The question I have is, in what way will it affect warranty? It should only affect the diff, nothing else especially considering MB actually has an LSD option. They going to say your engine blew as a a result of and LSD, I think not.

There is NO way they could void your engine, interior, gages, tec, from a POSI install.

I believe you are correct that indeed it would ONLY void your rear end warranty my friend. Back in the day after blowing out over a dozen Ford clutch pack posi's, they installed for free a Custom Auborn diff for me. But they did inform me that they would NOT honor ANY work that involved the rear end after installation.

(Unfortunately, the Quaife model for the 2011 and older E Coupes didn't fit the 2012 so they couldn't install. We need to get 2012 differential dimensions to Quaife)

(a)'12 C63 P/P, LSD, 19" m/spoke,comfort pack. (b)Astra SRI.
An LSD makes a big difference in the feel of the car. When you launch from a stop and the tires start to spin (TC off), the car will stay straight so it is much more predictable. It feels very unsafe and unpredictable without an LSD.
Also, when you are coming out of corners, you can use more throttle, earlier on, when you have a LSD.
I think overall, it adds a lot of balance to the car and the car feels overall more stable and tied down. It's less prone to wheel hop.

Couldn't have said it better myself!
We have optioned the LSD with our yet to be delivered C63, & for the life of me, I cannot understand why the C63 does not have one standard.....geez....450+ H.P......with no L.S.D???!!!......doesn't make sense to me.
