Testimonial - F20 M135i - Quaife LSD - Federico
my diff has been picked up this late afternoon and is on the way to Buckingamshire.
I did the first 15 minutes test drive on my preferred semi wet mountain road in the black forest.
What a pleasant difference with your diff! The notorious wheelspin on the inner rear wheels has disappeared completely and there is much more grip - the car therefore faster. Drifting now is easily possible and well controllable. It feels as if something missing until now has been finally activated.
I'll report my experience to the german forum.
Maybe I'll send you more feedback as soon as I find the time to drive and test.
