Product Information:
AC-Schnitzer 10,5x21 ET10
Philosophy/Design Technically modern design combined with a high-quality production process characterizes the AC Schnitzer AC6 Flowforming wheel generation,

available in sizes 10.0J x 20" and 10.5J x 21" in Svart and silver
Material

Only high-quality aluminum alloys are used. The material is additionally heat-treated during the production process, resulting in greater strength while simultaneously reducing weight.

Material samples taken during the manufacturing process ensure the consistent and high quality of the material.
Production

The new AC6 flowforming rims are measurably lighter than conventionally cast alloy rims thanks to the production process: the 10.0J x 20" rim weighs just 11.9 kg, and the 10.5J x 21" rim weighs only 12.9 kg.
The flowforming process is one of the most advanced manufacturing technologies in the wheel industry. In this production process, after the actual aluminum casting, the raw product is further processed by rolling it out. This step serves to compact the metal, which guarantees greater stability and impact resistance of the rim.
On the other hand, the improved stability also allows for even more delicate rim designs, as the wall thicknesses can be significantly thinner compared to conventionally manufactured rims.
Svart Finish

In this process, the wheel is first primed and then completely painted. A two-layer clear coat is then applied, consisting of a polyester primer and an acrylic clear coat.
Testing Procedure / Safety

After their design, the first sample rims are manufactured under real production conditions. These must undergo a variety 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 their homologation, i.e., approval for use on public roads.
Wheels are safety-relevant 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
