Philosophy/Design
The design of the one piece AC6 flowforming wheels combines delicate lightness with powerful presence. The dynamically shaped, slender Y-spokes are characteristic, extending to the wheel edge, thus visually increasing the diameter. Particularly striking is the pronounced concave dishing, which, with a depth of up to 90 mm on the rear axle, creates a spectacular appearance and impressively underscores the sportiness of the M models. This depth is not only a technical statement, but also a visual commitment to uncompromising performance.

Material
Only high quality aluminium alloys with the AlSi7 or AlSi11 specification are used. 
Both types of material are additionally heat treated in the production process, which results in higher strength and simultaneous weight reduction. Material samples during the production process guarantee the constant and high quality of the material.

Manufacture
The new AC6 flowforming wheels are lighter than conventionally cast alloy wheels thanks to the production process, and this is measurable: the 10.0J x 20" weighs just 11.9 kg, and the 10.5J x 21" wheel also weighs just 12.9 kg.

The flowforming process is one of the most advanced manufacturing technologies in wheel industry. In this production process, after the actual aluminium casting, the raw product is further processed by rolling it out. This step serves to compress the metal, which guarantees greater stability and impact resistance of the rim.

On the other hand, the improved stability also allows the design of the wheels to be more filigree, as the wall thicknesses can be significantly thinner compared to conventionally manufactured rims.

Surface Silver / Black
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.

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, the strength is tested. The "wheel life" is simulated in the bending circumferential test. Every AC Schnitzer wheel must withstand this intact in order to be allowed to be produced and sold at all.

This is followed by vehicle specific tests, including test installations with check of unobstructed movement and driving tests on public roads and on race tracks. Only after these procedures our rims receive their homologation, i.e. the approval to be used in road traffic.

Wheels are safety relevant components. Therefore, they are checked and tested with the greatest care. This starts with the first chemical material tests and ends with hard testing machine endurance runs:

- § 30 StVZO wheel guideline
- ECE R124
- Bending-rotation tests
- 90° impact test
- Unwinding tests
