The 7 generations of the Porsche 911 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. These measurements help you recognise your car; they are not a recommendation, and Onyx does not advise any specific offset.

Porsche 911: one icon, many faces

The Porsche 911 is more than a sports car: it is an automotive legend that has evolved for more than sixty years without ever betraying its DNA. From the original purity of the first models to the extreme performance of the most recent versions, each generation has its own character. Whether you are the keeper of a 911 G-model, a 964 with its timeless charm or an air-cooled 993, or you drive a 997, a 991 or the latest 992, your relationship with this machine is your own. It is to preserve and enhance that experience that we developed our range of custom wheels, designed to suit the spirit of each 911.

The technical advantage of forged wheels for your 911

Improving the performance of a Porsche 911 is a demanding engineering exercise. A particularly effective lever is the reduction of unsprung mass. Our forged wheels for the Porsche 911, machined from a block of forged 6061-T6 aluminium, offer a noticeable weight saving over cast alloy original equipment (OE) wheels. For the driver, the benefit is direct: better suspension response, sharper steering and crisper acceleration. On focused models such as a 991 GT3 RS or a 992 Turbo S, these gains make even more of the car's already considerable dynamic potential.

A custom look for each generation

The look of a 911 is a subtle balance between tradition and modernity. Our custom wheels for the Porsche 911 are created to respect and enhance that balance. Fully digital design and high-precision 5-axis CNC machining allow designs that blend with the style of each era. Whether it is a neo-retro look for a 964 'Restomod' or an aggressive, technical design for a 992 GT3, everything is possible. You choose the design and the finish; the Onyx Forged design office works out the technical specifications and submits them to you. We design your Porsche 911 wheels with a fitment optimised for your chassis, whether standard, lowered or fitted with oversized brakes, ensuring careful visual and functional integration, with no need for spacers.

Proven reliability and rigorous design

Performance is worth nothing without proven reliability. Every set of Porsche 911 wheels comes out of a rigorous design and finite element analysis (FEA) process. Our engineers model the mechanical stresses to make sure the structure meets the high demands of sporty driving, on the road as on the track. All our creations are designed to JWL/VIA standards. It is the assurance of fitting your 930 Turbo, 996 Carrera 4S or 991 Turbo with wheels whose design meets high quality standards, for confident, high-performance use.

Configure your custom Porsche wheels

Give your 911 a visual and technical signature of its own, worthy of its heritage.
