Hey Guys,
I've seen a couple of M3/5s with this sort of modification but I don't believe I've been able to find any Zs. First I'm wondering if anyone has found a product that could be installed on the Z4 (M) that would work and then second I'm trying to figure out of anyone has actually gone through with it. I'm not sure how such "upgrades" are perceived either but it has always been something very curious to me as you have yet another "option" on how to drive your beloved Z.
Here's an equivalent product (although I know there are nicer ones out there).
