This thread is about changing the final drive ratio. Turner Motorsport who knows what they are doing highly recommend the Wavetrac. I am absolutely happy with my choice but haven't compared side by side to other LSDs.

There is not much that can go wrong changing a diff so warranty wise it doesn't have a lot of implications I think.

Awesome, thanks!

So from what I gather with the Wavetrac you had to send them your stock diff for modification since it is a welded ring gear or do they send you a unit and you send back a core? Also, I don't see an M240i application with the 2.81 ratio. EDIT: Nor the Wavetrac option at Turner.
