APEX Wheels SM-10 Flow Formed Wheel | 18×9 ET42 | 5×112

Description

The APEX Wheels SM-10 from the Evolution Line represents a precision-engineered flow formed wheel designed for VW/Audi applications requiring 5×112 bolt pattern compatibility. This 18×9 ET42 wheel addresses the demands of performance applications through APEX’s flow formed construction process, which combines casting efficiency with enhanced strength characteristics to deliver optimal performance for track and street use.

The SM-10 achieves a weight of 21.0 lbs in the 18×9 configuration, providing unsprung weight reduction compared to factory VW/Audi wheels while maintaining the structural integrity required for performance driving. This weight control becomes critical in performance applications, where reduced unsprung mass directly improves handling dynamics, acceleration response, and braking performance.

The wheel utilizes flow formed construction, a manufacturing process that begins with a cast wheel blank before applying specialized forming techniques. During flow forming, the wheel barrel is spun at high speed while rollers apply controlled pressure, stretching and compressing the aluminum to create a denser grain structure. This process increases the material strength while reducing weight compared to traditional cast wheels, positioning flow formed construction between cast and forged methods in terms of both performance and cost.

The SM-10 features Profile 1 face design, providing the geometry suited for the 9-inch width configuration. The 57.1mm center bore specification provides precise hub-centric mounting for VW/Audi applications. The ET42 offset positions the wheel mounting surface to optimize suspension geometry and maintain proper brake clearance. The R13 ball seat hardware configuration ensures proper lug bolt engagement for the small bore application.

APEX offers the SM-10 in multiple finish options including Anthracite, Race Silver, Satin Bronze, and Satin Black to match various aesthetic preferences.
