Custom forged wheels for BMW M4

The BMW M4 is a sports coupé icon, combining raw power and a thoroughbred design. To enhance it further, Onyx Forged offers custom forged wheels. Cut from a single block of forged 6061-T6 aluminium, our wheels make your M4 lighter for greater agility and a more direct response. They give an exclusive visual signature and improved performance, matching the demands of this emblematic model of the M range.

The 2 generations of the BMW M4 compared

One row per published generation, from the oldest to the most recent. Each measurement comes from the generation's page, which cites its sources and gives the fitment of each version.

BMW M4: the heritage of a sporting icon

Since it first appeared, the BMW M4 has established itself as a benchmark among high-performance sports coupés. Succeeding the M3 Coupé, it kept its DNA while forging its own identity: an aggressive design, a sharp chassis and an engine with a strong character. Whether the first F82 generation or the very expressive G82, the M4 embodies a pure vision of driving pleasure. It is for the discerning owners of this model that we have developed a range of custom forged wheels, able to enhance both its style and its dynamic behaviour. Our BMW M4 wheels are designed to fit the car's philosophy: the pursuit of high performance.

Performance through lightness: the forged advantage

The secret of performance often lies in the details. For a sports car like the BMW M4, reducing unsprung mass is a key factor in improving handling. Our wheels, produced by a high-pressure forging process from blocks of 6061-T6 aluminium, offer a substantial weight saving compared with conventional alloy wheels. This lighter weight translates into more precise steering, more responsive suspension and stronger acceleration. The M4's engine, already very capable, can thus express itself even more freely. Each set of BMW M4 forged wheels is then finished by high-precision 5-axis CNC machining, for careful balancing and finishing.

A custom look for your BMW M4

The presence of a BMW M4 deserves a look to match. Onyx Forged lets you become the designer of your own wheels. Beyond the performance gain, our creations transform the appearance of your vehicle. You can choose from many designs, finishes and colours to create a set that reflects your personality. Whether you own an assertive-looking M4 G82, a more classic F82, a Competition version, a radical M4 CS or even the exclusive CSL, we adapt every parameter. The wheel position you choose is translated into measurements, width and offset, which are submitted to you before machining. These custom BMW M4 wheels are the finishing touch that sets your car apart.

Reliability and design for high performance

The power of a BMW M4 places high demands on safety and reliability. At Onyx Forged, a French brand of custom wheels, we take these constraints into account from the very first design stage. Our BMW M4 wheels are designed to JWL/VIA standards. The sizing takes sporty driving into account, on the road and on track. By choosing our BMW M4 forged wheels, you opt for a solution that combines a personalised look with rigorous design, for an improved driving experience.
