BBS CH-R Cast Flow-Formed Aluminium Alloy Wheels

BBS CH-R - The Flow-Formed Split-Spoke Wheel With a Motorsport Pedigree

The Split-Spoke Face That Reads as Motorsport

The BBS CH-R was not designed to be subtle. Its split-spoke geometry is a direct reference to the wheels BBS developed for GT racing - long, angled spokes that give the face a sense of motion even when the car is stationary. It is a design that announces its intent before the car moves, and it has become one of the most recognisable shapes in the BBS catalogue because of it.

Where Flow-Forming Meets Casting

The CH-R is produced using BBS's counter-pressure casting process, followed by flow-forming of the rim area - the same technology the brand introduced to the aftermarket in 1996 and has refined over decades of motorsport and OEM supply. During flow-forming, the cast blank is heated and rolled under high pressure, compacting the material and aligning its grain structure. This increases strength and stiffness while reducing weight, and it allows the CH-R to achieve a stiffness-to-weight ratio that a conventional cast wheel cannot approach. BBS develops this geometry in-house, and no replica producer has access to the tooling or the thermal treatment process.

The CH-R Design

The CH-R's defining feature is its long, angled split-spoke pattern - a design that has become a reference point for enthusiasts because it looks equally correct on a Volkswagen Golf R and a Porsche Cayenne. The spokes are back-milled to remove unnecessary material, and the wheel includes a replaceable stainless-steel rim protector - a detail that protects the rim edge from kerb damage. The face is visually dynamic, but the flow-formed barrel ensures that the density does not come at the cost of performance. It is a wheel that reads as motorsport-derived without looking overstated.

For Cars That Demand Motorsport-Derived Engineering

The BBS CH-R suits owners of Volkswagen Golf R, Audi S4, and Porsche Cayenne - cars where the wheel must perform under load and look correct at every viewing distance. Tell us which car you are building for, and we will confirm the CH-R specification before the order is signed off.
