Apex SM-10RS 18x9 Forged Wheel - 5x130 BP / ET46 / 71.6mm CB - Anthracite (SM10RS189ET46-5130-716-AN)
The Apex SM-10RS is engineered for enthusiasts who demand lightweight performance without sacrificing strength, stiffness, or durability. As part of Apex's Sprint Line of forged wheels, the SM-10RS combines cutting-edge forging technology with motorsport-focused engineering to create a wheel capable of excelling on both the street and the track.
Constructed from a massive 6061-T6 aluminum forging formed under an incredible 10,000 metric tons of pressure, the SM-10RS achieves exceptional strength through enhanced grain structure and reduced porosity. Combined with Apex's proprietary motorsport-specific forging blanks, this wheel delivers outstanding brake clearance, optimized weight savings, and race-ready durability for serious driving enthusiasts.

Forged Motorsport Engineering
The SM-10RS begins life as a forging weighing up to 120 pounds before machining. The immense pressure used during the forging process improves aluminum density, strengthens grain structure, and eliminates porosity, creating an exceptionally strong foundation. Unlike many manufacturers that rely on generic third-party forgings, Apex developed proprietary motorsport-specific blanks that maximize brake clearance, spoke geometry, wheel concavity, and overall performance.
Extensive Finite Element Analysis (FEA) was used throughout development to reinforce high-stress areas while removing material that offered no measurable strength benefit. This engineering process results in a wheel that remains exceptionally lightweight without compromising durability.
Advanced I-Beam Spoke Design
One of the most recognizable features of the SM-10RS is its side-milled I-beam spoke architecture. Precision CNC machining removes excess material from both sides of each spoke, reducing rotational mass while maintaining exceptional rigidity. This advanced design maximizes steering response and stiffness without increasing weight.
The result is a wheel that is nearly identical in weight to the popular VS-5RS while delivering almost 10% greater stiffness and approximately 25% greater stiffness than Apex's first-generation forged wheel designs.
Built for Track and Street Abuse
The SM-10RS incorporates a reinforced Sprint Spec inner lip that improves impact resistance while maintaining low weight. Paintless knurled bead seats help prevent tire movement during aggressive acceleration and braking, while massive brake clearance and application-specific spoke profiles support a wide range of factory and aftermarket brake systems.
To validate durability, Apex utilizes independent testing through STL in Ohio. Sprint Line wheels undergo testing beyond traditional JWL standards using increased loads, extended testing durations, and more severe impact testing procedures.
