M3 bits including subframe bushings, Dinan Camber plates, Swift Springs, Koni Yellows and a few more odds and ends. I initially had the Konis set pretty soft, I think I did the equivalent of 40% front and rear. Didn't like the feel on the track at all. Set it for 75% front and rear and the car handles amazing on the track. It's pretty rough on the street though, although it eats up those corners. It's primarily a track type car. It drives to and from the track events, now and then on the weekends but that's it. Its obviously not my DD. I run Apex ARC 8s with Hancook RS3s, 235/255. Not a great steet tire, as they are loud and harsh, but on the track you can't beat them. Here's my video from my last track day.
