Apex SM-10RS 18x9 Forged Wheel - 5x130 BP / ET46 / 71.6mm CB - Brushed Clear (SM10RS189ET46-5130-716-BC)
The Apex SM-10RS is engineered for enthusiasts who demand lightweight performance without compromising strength, stiffness, or durability. As a member of Apex's Sprint Line of forged wheels, the SM-10RS combines advanced forging technology with motorsport-focused engineering to deliver exceptional performance on the street, at the track, and everywhere in between.
Manufactured from a massive 6061-T6 aluminum forging formed under an incredible 10,000 metric tons of pressure, the SM-10RS benefits from enhanced grain structure and reduced porosity for outstanding strength. Combined with Apex's proprietary motorsport-specific forging blanks, this wheel offers exceptional brake clearance, optimized stiffness, and race-ready durability while maintaining an impressively low weight.

Forged for Serious Performance
The SM-10RS starts as a forging weighing up to 120 pounds before machining. The immense pressure used during the forging process refines the aluminum grain structure, eliminates porosity, and creates an exceptionally strong foundation. Unlike manufacturers that rely on generic third-party forgings, Apex developed proprietary motorsport-specific forging blanks that maximize brake clearance, spoke geometry flexibility, wheel concavity, and overall performance.
Extensive Finite Element Analysis (FEA) was utilized throughout development to reinforce high-stress areas while removing material that offered no measurable strength advantage. The result is a wheel that remains remarkably lightweight without compromising durability.
Advanced I-Beam Spoke Engineering
One of the most distinctive 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 enhances steering response, stiffness, and overall vehicle feedback without increasing wheel weight.
The result is a wheel that delivers nearly identical weight to the popular VS-5RS while providing almost 10% greater stiffness and approximately 25% greater stiffness than Apex's first-generation forged wheel designs.
Built for Track Abuse
The SM-10RS incorporates a reinforced Sprint Spec inner lip designed to improve impact resistance while preserving lightweight performance. Paintless knurled bead seats help prevent tire movement during aggressive acceleration and braking, while massive brake clearance and application-specific spoke profiles accommodate a wide variety of factory and aftermarket brake systems.
To verify real-world durability, Apex utilizes independent testing through STL in Ohio. Sprint Line wheels undergo testing beyond traditional JWL standards using increased loads, longer testing durations, and more severe impact testing procedures.
