Well I did it cut the stock boot off and did the custom ZHP lighted knob, pretty easy with the right tools and some patience. Anyway pretty happy with the turnout, only issue I had was I nicked a small portion of the outside edge of the ZHP with the dremmel
but it's not that notable. I must say that for an M3; BMW should have done better with the shifter, the ZHP is soooooooooo much better. For those of you still on the fence about doing the swap, go for it.
