BBS LM Forged Aluminium 2-Piece Wheels

BBS LM — The Flow-Formed Two-Piece Wheel Inspired by Le Mans

The Design That Defined a Genre

Some wheels are designed to follow trends. The BBS LM was designed to set one. First introduced in 1994 and named after the 24 Hours of Le Mans — the endurance race where BBS racing wheels won for decades — the LM is the wheel that defined what a two-piece mesh design should look like. Its cross-spoke face and diamond-cut rim have become a reference point for enthusiasts around the world, and the design has remained in continuous production for over thirty years because it was resolved correctly the first time.

Where Flow-Forming Meets Two-Piece Construction

The LM 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 rim is flow-formed separately, allowing BBS to achieve a rim well thickness of just 2.25 mm — significantly thinner and lighter than a conventional casting. 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.

Why Flow-Forming Matters on the LM

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 LM, this translates into a measurable reduction in unsprung mass — approximately 20% compared to a traditional cast alloy wheel of similar dimensions. The result is sharper turn-in, quicker acceleration, and improved braking response. The LM's two-piece construction also allows for a wider range of offsets and lip depths than a one-piece design, which is why it remains a favourite for everything from Porsche 911s to JDM legends.

For Drivers Who Value Proven Design

The BBS LM suits owners of Porsche 911, BMW M3, and Nissan Skyline GT-R — cars where the wheel must be both visually correct and technically capable. Every specification is validated against the individual vehicle before production begins. Reach us to begin your fitment review.
