BBS 2088061 Wheel RT88 for PORSCHE 911 GT3 RS (992) 21x13 ET31, Center Lock, Black Bright Diamond Cut

Description BBS 2088061 Wheel RT88 for PORSCHE 911 GT3 RS (992) 21x13 ET31, Center Lock, Black Bright Diamond Cut

The BBS RT88 wheel combines authentic motorsport engineering with the durability required for modern high-performance road and track vehicles. Developed through collaboration between BBS Motorsport teams in Germany and the United States, the RT88 brings the legendary design philosophy of the iconic BBS E88 racing wheel into a road-ready configuration.

The wheel features a forged multi-spoke center inspired by the famous E88 race wheel, paired with a high-strength forged barrel derived from the BBS LM program developed in Japan. This advanced two-piece forged aluminum construction increases structural rigidity while significantly reducing unsprung mass, improving steering precision, braking performance, and overall vehicle dynamics.

Unlike pure racing wheels, the RT88 is engineered with durable road-ready finishes and enhanced sealing technology designed to withstand real-world driving conditions such as temperature variations, road impacts, and long-term use. The structure is optimized through FEM analysis to achieve the ideal balance between strength, stiffness, and weight reduction.

This version features the premium Black Bright Diamond Cut finish and is specifically designed for Porsche 992 GT3RS models equipped with center lock hubs. The design also provides excellent clearance for large performance braking systems including carbon ceramic brakes.
