Philosophy/Design
A technical and visual revolution: The AC Schnitzer Type VIII forged racing wheel. When light-alloy wheels consist of more than one component, they are referred to as multi-piece light-alloy wheels. Three-piece AC Schnitzer light-alloy wheels consist of two rim halves and the rim centre. The Type VIII forged racing wheel is based on the design of the Type VIII rim, but has a lot more to offer. This genuine, three-piece design product is a revolution in the large market environment for popular wire-spoke rims and fits perfectly with BMW's design language. The visual charm of the rim with its classic 5-twin spokes results from the cast, forged, and machined inner centre and the anthracite spoke frame. The visible screw connections to the rim wells are entirely intentional. The stainless steel screws simultaneously document the multi-piece design and the associated exclusivity of the rim. The outer and inner rim wells are made of forged material manufactured using the flow-forming process. Despite all the details, the multi-part VIII forged racing wheel doesn't appear playful, but rather masculine and sporty thanks to its straight lines. - 3-part rim - visible screw connection with stainless steel screws - particularly stable - Outer rim: forged, milled, rolled, and clear-coated - Rim centre: forged, milled, and painted black - Inner rim: aluminium block, milled, rolled, and anodised in anthracite - Surface: turned, clear-coated - Lightweight inner centre, using forging technology - Weight reduction through forging technology - Reduction of unsprung mass and gyroscopic forces on the car, resulting in significantly increased driving dynamics - Better acceleration and deceleration due to lower masses - Improved cornering - Striking, sleek design in anthracite with silver - High-quality clear coat to protect the rim against corrosion, resulting in a long service life - Exclusive look of the forged racing wheels
material
Rim star: Forged block made of high-strength aluminium Outer rim: High-strength aluminium Inner rim: High-strength aluminium
production
Steps on the way to perfection - Forged rim star - Outer rim deep-drawn, CNC-machined, high-gloss polished and clear coated - Inner rim deep-drawn, CNC-machined, anodised The individual components are connected to one another using high-strength titanium screws.
Bicolour silver/anthracite surface
In this process, the wheel is first primed and then completely painted. The surfaces that will later have a metallic luster are then turned and polished to a high gloss. Finally, a two-coat clear coat is applied, consisting of a polyester primer and an acrylic clear coat. Outer Rim / Surface: In this process, the outer rim is first polished to a high gloss. Then, a two-coat clear coat is applied, consisting of a polyester primer and a glossy acrylic clear coat. Inner Rim / Surface: The inner rim is anodised.
Test procedures / safety
After their design, the first sample rims are manufactured under real production conditions. These must undergo a multitude of tests. Among other things, their strength is tested. The bending test simulates the "rim lifespan." Every AC Schnitzer rim must survive this lifespan unscathed in order to be produced and sold. Vehicle-specific tests, including test installations with clearance measurements and driving tests on public roads and racetracks, follow. Only after these procedures do our rims receive homologation, i.e., approval for use on public roads. Wheels are safety-critical components. Therefore, they are inspected and tested with the utmost care. This begins with initial chemical material tests and concludes with rigorous endurance tests on test machines: - §30 StVZO wheel guidelines - ECE R124 - Bending tests - 90° impact test - Rolling tests
