Dan has built clutch-based diffs for my track and race cars, and I recommend diffsonline highly. For sure check them out.

The helical gear-based Wavetrac that Dan built for me has made a big difference in my M240i, and I'm looking forward to what it can do for me at Mid-Ohio's handling track this weekend.
As someone not in the know as someone like yourself, can you explain the real difference between something like the Wavetrac and the M LSD? Of course, price for one, but what is real world for someone who will not track often but just wants to put the power to the ground a little better (in a 6spd).

Also, I know if I get the BMW M LSD in there my warranty is still fine. What about with a Wavetrac or similar? Obviously the diff wouldn't be covered by BMW but would it be likely for BMW to deny ANY drivetrain warranty claim if using a non BMW diff?

Thx
