BBS G90 / G99 M5 FI-R 21" Wheel Set

The BBS FI-R forged wheel set for the BMW G90 and G99 M5 represents the latest evolution of BBS lightweight forged wheel technology. Designed and manufactured by BBS Motorsport in Germany, the FI-R combines advanced forging techniques with extensive CNC machining to create an ultra-lightweight wheel engineered for high-performance vehicles.

One of the defining characteristics of the FI-R is the aggressive weight-reduction machining visible throughout the spoke structure. These precisely milled pockets remove excess material while maintaining the structural rigidity required for modern high-performance vehicles such as the BMW M5. The result is a forged wheel with an exceptional stiffness-to-weight ratio that helps improve steering precision, suspension response, and overall chassis feedback.

BBS forged wheels begin as a high-grade aluminum billet which is shaped using BBS’s proprietary multi-stage die forging process. This manufacturing technique compresses the material under immense pressure, refining the grain structure and producing a wheel that is both lighter and stronger than traditional cast wheels.

For performance platforms like the G90 M5 and G99 M5 Touring, reducing unsprung mass plays a critical role in improving vehicle dynamics. A lighter wheel allows the suspension to react faster to road inputs while improving braking consistency and steering response during spirited driving.

The FI-R has become one of the most recognizable wheels in the BBS lineup thanks to its motorsport-inspired design and functional engineering. Combined with vehicle-specific fitment for the newest BMW M5 platform, the FI-R delivers both performance gains and an unmistakable motorsport aesthetic.
