Larger, lighter, more filigree and stronger: the new, exclusive AC3 Flowforming wheels from AC Schnitzer

With the new AC3 Flowforming wheels the refinement specialists from AC Schnitzer enrich the wheel market for many current BMW series and realise what at first sight seems contradictory: reduction in weight with simultaneously increased wheel diameters.

9 or 10 x 21 inch are the dimensions of the brand new AC3 Flowforming wheels. Two colour variants are available in BiColor silver/anthracite or anthracite matt. Visually, the new rims can be clearly assigned to the AC3 rim family and they complement the portfolio in terms of sizes, areas of application and manufacturing processes.

The filigree and particularly large-looking spoke matrix of the AC3 Flowforming rims with their five triangular struts have been weight-optimised using a very special production process.

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.

And this is measurable: compared, for example, with the BMW forged rim "Double Spoke 706 M" for the M5, which at 10.5J x 20" is even one inch smaller than the new AC3 Flowforming rims, these are 2.4 kg and 2.5 kg lighter than the BMW rim and this has an impact.

The lower weight of the AC3 Flowforming rims reduces the unsprung masses on the vehicle by about 10 kg and thus also reduces the CO2 emissions of the vehicle. At the same time, there is also a noticeable improvement in driving dynamics, as the gyroscopic forces on the axles are reduced by about four times - by a perceived 40 kg. The AC Schnitzer AC3 Flowforming wheels therefore offer real advantages: for the driver and the environment.
