183 a month?!?!?!?!? Sweet Jesus. I pay 81 for full coverage on the M3 and basic coverage on the 535i. 6 tickets and 2 accidents? You need to take it easy... how do you still have license? That is insane. Need to do some track days so you get bored of driving around on the street and getting 6 tickets and 2 accidents

Suspension geometry? To my knowledge your front control arms and bushings are different. To get the same geometry from the late model you simply put on the late model control arms and centered bushings. Past that I do not know of anything different. ASC is a moot point, simply turn off the ASC or disable it

TRM will have a plug and play and flash tuned OBD2 turbo soon. Thus the stronger m52 is the answer

3.23 or 3.38 diff - M50 manifold - M3 Cams - Intake - Exhaust - Tune and we are close to equal. Barely spent anything. I will skip all that though and wait for turbo. Not going for racing, definitely not street racing so it really doesn't matter. May not ever turbo. Cruiser car

Consider on a 328i you have 300-400 pound advantage. That makes a huge difference.
