M3/M4 F8X BBS LM-R 20" Wheel Set

The BBS LM-R is a motorsport-derived forged wheel engineered for drivers pushing the limits of performance. Built using BBS’s proprietary multi-stage die-forging process, each wheel is produced under extreme pressure to maximize strength while minimizing weight. The LM-R takes the classic LM design and reinforces it for higher loads, making it ideal for aggressive street builds and track-focused applications.

This 20" staggered configuration is designed for F8X M3 / M4 platforms seeking a wider, more aggressive stance with increased track width and enhanced grip potential.
