Installation
Installation costs are usually 200 to 300 € when done by a professional, but it's not very hard to install it by your self.

The Quaife differential it's self is precisely manufactured to original specs. Assuming the original differential units of the car are as precise, shimming is not required all though it is good to check when you're at it.

It is important to keep bearings and shim plates in the original order, as changing the side or order can also change the pinion shimming. If you want to install the unit your self, check out YouTube for some videos or ask a friend to help you out. Installation is easy as long as you know what you're doing, and on-line guides are widely available for most applications.

Recommended oil
The Quaife tosen requires non-lsd oil. The LSD-additives are basically friction modifiers which reduce friction, in turn hurting the optimal operation of the differential. A good example of oil is the Red Line NS-range. More info on oils Quaife technical Q&A

Warranty
Quaife's lifetime warranty covers differential problems apart from natural wear, provided lubrication has been taken care of. Warranty also covers motorsport and competition use.
