BBS SUPER-RS Flow Formed Aluminium 2-Piece Wheels

BBS Super RS - The Flow-Formed Two-Piece Wheel That Defined a Generation

The Design That Never Needed a Revision

Some wheel designs arrive and disappear within a few seasons. The BBS Super RS arrived in 1983 and has never left. Its seventeen cross spokes and luxurious styling have remained unchanged for over forty years - not because BBS stopped innovating, but because the design was resolved correctly the first time. It is a wheel that has become a reference point for enthusiasts around the world, and it remains in continuous production because it works on almost anything it is fitted to.

Where Flow-Forming Meets Two-Piece Construction

The Super RS is produced by BBS Japan using a combination of technologies that reflects the brand's motorsport heritage. The centre face begins as a high-quality aluminium blank, which is heated and flow-formed under extreme pressure to create a dense, fine-grained metal structure. The outer barrel is flow-formed separately, and the two components are then joined using exposed stainless hardware - a construction that allows for precise assembly and, uniquely for this category, the ability to replace the outer rim if it is damaged. This is a wheel built to be serviced, not simply replaced. BBS develops this geometry in-house, and no replica producer has access to the tooling.

Why Flow-Forming Matters on the Super RS

Flow-forming is not a marketing term - it is a metallurgical process. By spinning the aluminium blank against hydraulic rollers at high temperature, BBS compacts the material and aligns its grain structure, producing a wheel that is both lighter and stronger than a conventional cast alternative. On the Super RS, this translates into a wheel that weighs approximately 10.7 kg in its lightest configuration, while delivering the structural integrity that a two-piece construction demands. The two-piece design also allows for a wider range of offsets and lip depths than a one-piece wheel, which is why it remains a favourite for everything from Toyota Supras to Porsche 911s.

For Drivers Who Value Proven Design

The BBS Super RS suits owners of Toyota Supra, Porsche 911, and Mercedes-Benz SL - cars where the wheel must be both visually correct and technically capable.
