Apex SM-10RS 18x9 Forged Wheel - 5x130 BP / ET46 / 71.6mm CB - Satin Black (SM10RS189ET46-5130-716-NSBK)
The Apex SM-10RS was developed for enthusiasts seeking the ideal combination of lightweight performance, exceptional stiffness, and race-proven durability. As part of Apex's Sprint Line of forged wheels, the SM-10RS leverages advanced forging technology and motorsport-focused engineering to deliver uncompromising performance on the street and at the track.
Manufactured from a massive 6061-T6 aluminum forging formed under an incredible 10,000 metric tons of pressure, the SM-10RS achieves outstanding strength through improved grain structure and reduced porosity. Combined with Apex's proprietary motorsport-specific forging blanks, this wheel delivers exceptional brake clearance, optimized weight reduction, and durability that serious drivers can depend on.

Forged Motorsport Engineering
The SM-10RS starts as a forging weighing up to 120 pounds before machining. The immense pressure utilized during the forging process refines the aluminum grain structure, improves material density, and eliminates porosity, resulting in an exceptionally strong foundation. Unlike manufacturers that utilize generic third-party blanks, Apex designed proprietary motorsport-specific forgings 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 unnecessary material. The result is a wheel that remains exceptionally lightweight without sacrificing strength or durability.
Advanced I-Beam Spoke Technology
One of the defining characteristics 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 engineering approach improves steering response, wheel stiffness, and overall vehicle feedback without increasing wheel 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 Serious Driving
The SM-10RS features a reinforced Sprint Spec inner lip designed to improve impact resistance while maintaining lightweight performance. Paintless knurled bead seats help prevent tire movement during hard acceleration and braking, while massive brake clearance and application-specific spoke profiles accommodate a wide range of factory and aftermarket brake systems.
To verify 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.
