When it comes to refining the driving experience of BMW M platforms, precision in fitment and finish is everything. The RAYS 21A delivers exactly that—combining classic multi-piece design language with a specification engineered specifically for modern M cars.

Developed as a custom size configuration for BMW M models, this setup is purpose-built to suit platforms such as the M2, M3, and M4. With sizing dialed in at 18 x 9.5 +22 (front) and 18 x 10.5 +30 (rear) in 5x120 PCD, the fitment achieves a balanced stance without compromising drivability or clearance. It’s a specification that works with the chassis—not against it.

A key highlight of this setup is what it represents visually and functionally. The 21A delivers a design language comparable to the iconic BBS LM style—something traditionally unavailable in true 18-inch sizing for track-focused enthusiasts. This opens up a rare combination: classic multi-piece aesthetics with a more practical diameter suited for performance driving, tyre selection, and track use.

What sets this release apart is its exclusive finish, created in-house by KA Autosport Pty Ltd. The wheel features a gold centre paired with a diamond-cut lip, blending a heritage-inspired tone with a sharp, modern edge. The gold centre introduces warmth and depth, while the diamond-cut lip adds contrast and definition—enhancing the multi-piece aesthetic and emphasizing the wheel’s proportions under light.

The RAYS 21A itself brings a timeless silhouette, but in this configuration, it becomes something more focused—something tailored. The combination of custom sizing and bespoke finishing transforms it from a standard offering into a platform-specific solution.

Exclusively available through KA Autosport Pty Ltd, this setup is designed for BMW M owners who demand more than off-the-shelf options. It’s not just about appearance—it’s about achieving the right balance of form, function, and individuality.

A refined approach to fitment. A considered execution of design. This is RAYS 21A, redefined for BMW M.
