yeah I got the shifter from the Mz3 and the ZHP knob. Made it much more notchy, but shortened the throw significantly. The whole setup was around 75-100 so totally worth it in my opinion. I'm about 5'7" and the throw made me lean forward in the seat or I'd miss the 2-3 or 4-5.
The steering just feels slow to me. I have an MG that I think, and I'm in that direction. The M3 was like a bus in comparison. It ain't just the big steering wheel. The MG's is 14". It could easily do with a 30% increase in quickness (however you call the ratio) in my opinion. It's a sportscar.
The engine was sublime though. Just spectacular. I'd almost (almost) not add any power to it.
