Posted this in the DIY thread as well...
Well I finally did this mod....had to take my car the local german car mechanic because I couldnt figure out my stumbling issue - so I had him install it while he had the car on the lift... When I got the car back, the shifter now sits 1-2" forward in neutral than beforeshifting 1st,3rd,5th is now pushing up against the center console, 2nd and 4th now sits where neutral used to be. He claims that the shifter arm underneath is too short. He's also asking me to ask you guys how long is the shifter arm from lever to trans so he can adjust a "fix" to it. I'm not quite sure thats necessary as all you have done it without issue.
I questioned him to a point without insulting him but what did he do wrong so I can correct it later myself? I used the Z3 1.9 shifter from BMA. Other than the way it sits...it shifts wonderfully...notchy and weighted, similar to the way my 350z is but tighter.
