looking at having one of these installed into my z4 3.0i

was wondering if anyone had made the same move and had some feedback?

For track use, road or both?

i had on on my 130i and it was a fabulous bit of kit, really was awesome....

it performed every bit as good as my ///M Differential in the z4m.....
The only gripe was it could ne noisey but that didnt bother me at all but probably would others... go for it you will not regret it.

It's primary purpose is a road car but it will see some track action now I'm not as scared about scratching it lol
