I've been driving the car now for a few weeks, and the difference between the M52 and S52 is amazing. The Z3 rack-n-pinion really awakens the car, too. I had it aligned to 3.1 degrees negative up front (using the M3 hubs add negative camber over the 328i setup that they replaced), and essentially zero toe -- so it is a bit "darty" but also very alive. The red-poly trans mounts really do increase the in-cabin vibrations, but the shifts are crisp. My first autocross (PCA Central Coast region, at the Santa Maria Airport) is this Saturday, so I'll get to really wring it out and compare my times to other cars I'm used to playing with. Unfortunately, my wife's back is not doing well, so the Z3 M Roadster will remain in our driveway... __________________
