Description
The APEX Wheels SM-10 from the Evolution Line represents a precision-engineered flow formed wheel designed for Porsche applications requiring 5×130 bolt pattern compatibility. This 18×8.5 ET50 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 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 the 71.6mm center bore specification, providing precise hub-centric mounting for Porsche applications. The ET50 offset positions the wheel mounting surface to optimize suspension geometry and maintain proper brake clearance for the 5×130 bolt pattern platform. This offset configuration works specifically with the 8.5-inch width to deliver appropriate wheel placement within the wheel well while accommodating performance brake upgrades commonly found on Porsche platforms.
The SM-10 features Profile 1 face design, providing the geometry suited for the 8.5-inch width configuration. APEX offers the SM-10 with R14 Ball Seat hardware specifications for proper lug nut compatibility. The wheel is available in multiple finish options including Anthracite, Race Silver, and Satin Black to accommodate different aesthetic preferences while maintaining the same performance characteristics across all finish variants.
