I thought this may be helpful for those shopping for a BBK and wheels. Let's focus on 18" wheels because 19" wheels should clear most BBK on the market for M3. Also, rear kits other than the ones listed below should work on 18" wheels.

Please respond with your BBK and wheel specs. I will compile everyone's input and update this post as often as I can.

Disclaimer: many variables can affect BBK - wheel fitment compatibility. Always check the clearance after installing new components. When in doubt, consult with your supplier and/or manufacturer. Use information below at your own risk.
