Porsche 718 Boxster: open-top agility

The Porsche 718 Boxster is the very essence of the sports roadster. With its mid-engined layout, it offers a balance and an agility that delight driving purists. From the liveliness of the base 718 Boxster to the precision of the Boxster T or the power of the Boxster S, each version is a celebration of the pleasure of driving. The experience is direct, connected to the road. For discerning owners who want to bring out these qualities, the choice of wheels is a crucial step, influencing the look, the handling and the overall performance of the car.

Onyx Forged, a French brand of forged wheels, offers a custom solution to take your Boxster's potential further. Replacing the original equipment (OE) wheels with a set of custom forged wheels is not a simple cosmetic modification; it is a technical improvement that directly affects the dynamics of this remarkable chassis.

The advantage of custom forged wheels for the 718 Boxster

The main advantage of forged wheels lies in a significant reduction in unsprung mass. A lighter wheel lets the suspension work more effectively, improving the tyre's contact with the road, steering response and cornering precision. For a roadster as agile as the 718 Boxster, this gain translates into a feeling of lightness and an even more intense connection with the machine.

Our Porsche 718 Boxster wheels are shaped exclusively from a block of 6061-T6 aluminium. This material goes through a high-pressure forging process. The result is a lighter wheel, an undeniable asset for sporty driving.

Exacting looks and design

Beyond performance, looks are an essential criterion for Porsche owners. Our 718 Boxster forged wheels are machined on 5-axis CNC machines, a technology that makes complex designs and very fine finishes possible. Whether you want a sober, elegant style for your Boxster or a bolder design for a GTS 4.0 or a Spyder, a custom set gives you complete freedom.

Each set of custom 718 Boxster wheels is configured to your preferences, but also and above all to the technical specifications of your car. We adjust the offset (ET) and the width to obtain a perfect flush fit with the bodywork (fitment), giving your 718 a wider, more assured stance. This approach ensures a careful visual integration that standard wheels do not always achieve.

Proven reliability and performance

Performance must never come at the expense of safety. That is why every design of Porsche 718 Boxster wheels is rigorously thought out for high reliability. Our wheels are designed to JWL/VIA standards.

This rigorous approach ensures that your 718 Boxster forged wheels are ready to take the stresses of dynamic driving on winding roads as well as those of an occasional track day. This commitment is a source of peace of mind, letting you make full use of the capabilities of high-performance models such as the 718 Cayman GT4 or the Boxster 25 Years.

Configure your custom Porsche wheels

Every Porsche owner has a vision of their car that is their own. Onyx Forged helps you bring that vision to life by creating a set of wheels that is yours alone. From the initial design to the 3D render on request, we offer you a complete personalisation experience to give your 718 Boxster or Cayman a set of wheels that is as high-performing as it is exclusive. Configure your custom wheels.
