BBS 2088046 Wheel RT88 for AUDI RS4 / BMW M5 (F90) VA 21x10 ET25 5x112
Description BBS 2088046 Wheel RT88 for AUDI RS4 / BMW M5 (F90) VA 21x10 ET25 5x112
The BBS RT88 wheel represents a motorsport-derived design engineered to combine authentic racing heritage with the durability required for modern high-performance road vehicles. Developed through close collaboration between BBS Motorsport divisions in Germany and the United States, the RT88 translates the engineering philosophy and iconic styling of the legendary BBS E88 race wheel into a configuration suitable for both street use and demanding track-day conditions.
The design incorporates a forged multi-spoke center inspired by the E88 paired with a high-strength forged barrel derived from the BBS LM wheel program developed in Japan. This advanced construction significantly improves structural rigidity while reducing unsprung mass, enhancing steering precision, suspension response, and overall vehicle dynamics. Unlike pure racing wheels, the RT88 features durable finishes and optimized air retention to ensure reliable long-term operation in real-world driving conditions.
Manufactured using advanced die-forging processes and optimized through FEM structural analysis, the RT88 achieves an exceptional strength-to-weight ratio. The wheel is engineered to accommodate modern high-performance braking systems, including large brake packages and carbon ceramic brakes commonly found on performance-oriented vehicles.
- Two-piece forged aluminum construction with forged center and die-forged barrel
- Motorsport mesh design inspired by the legendary BBS E88 race wheel
- Forged barrel technology derived from the BBS LM wheel program
- Weight-optimized structure engineered through FEM analysis
- High rigidity and durability for road and track-day performance
- Designed to clear large performance braking systems including carbon ceramic brakes
- TPMS compatible with valve stems included
- Available finishes include Gold, White Gold, Silver, Black (Satin / Glossy), and Midnight Gold
Specifications:
- Wheel Diameter: 21 inch
- Wheel Width: 10J
- Offset: ET25
- Bolt Pattern: 5x112
- Construction: Two-Piece Forged Aluminum
