No. It is a continuous variable locking diff which they have a patent on I believe and can lock form 0-100-0 depending on load axle speed. It is also warrantied for life. Can't go wrong with the Quaife. Every car should have one. Read up on their web site for some good info.

Pretty sure its only 80% for the aftermarket one. The one in the e92 M3 is 0-100-0.

Have a look here:

Give us a call if you have any other questions. We were one of the very first to install the Quaife in the 335i and have done most of the installs and provided tech support on this unit.
