Apex SM-10RS 19x12 Forged Wheel - Porsche Center Lock / ET47 / 101mm CB - Anthracite (SM10RS1912ET47-CL-PS-AN)
The Apex SM-10RS is the ultimate expression of lightweight forged wheel engineering, designed for drivers who demand uncompromising performance on both the street and track. As part of Apex's Sprint Line, the SM-10RS combines cutting-edge forging technology, extensive Finite Element Analysis, and motorsport-driven design to create a wheel that is exceptionally light, remarkably strong, and engineered to thrive under extreme conditions. Finished in Anthracite and built specifically for Porsche center lock applications, this 19x12 wheel delivers the strength, stiffness, and brake clearance serious enthusiasts expect.
Each SM-10RS begins as a proprietary 6061-T6 aluminum forging weighing up to 120 pounds before machining. Formed under 10,000 metric tons of pressure, the forging process improves grain structure while reducing porosity for maximum strength. Apex then utilizes advanced engineering techniques to remove unnecessary material and reinforce critical load-bearing areas, creating a wheel that offers exceptional durability without the weight penalties commonly associated with stronger wheel designs.

Advanced Forged Performance
Unlike conventional forged wheels that focus solely on reducing weight, the SM-10RS was engineered to achieve the ideal balance of weight savings, strength, and stiffness. Apex strategically removed material where it was unnecessary and reinforced critical areas to create a wheel capable of handling demanding track use while maintaining outstanding responsiveness.
I-Beam Spoke Technology
The signature I-beam spoke design is created through extensive side milling on both sides of every spoke. This machining-intensive process removes excess material that does not contribute to strength, resulting in a lighter wheel without sacrificing structural integrity.
Sprint Spec Inner Lip
The reinforced Sprint Spec inner lip features a unique channel profile that increases strength in one of the wheel's most critical impact zones. Even though the SM-10RS is significantly lighter than many comparable wheel options, its inner lip is engineered for exceptional durability.
Fitment
