Apex SM-10RS 18x9 Forged Wheel - 5x114.3 BP / ET23 / 60.1mm CB - Satin Bronze (SM10RS189ET23-51143-601-NSBZ)
The Apex SM-10RS is engineered for enthusiasts who demand lightweight performance, exceptional durability, and uncompromising strength. As part of Apex's Sprint Line of forged wheels, the SM-10RS combines advanced motorsport engineering with cutting-edge manufacturing processes to create a wheel capable of excelling on the street, at the track, and everywhere in between.
Manufactured from a massive 6061-T6 aluminum forging formed under 10,000 metric tons of pressure, the SM-10RS delivers outstanding strength through enhanced grain structure and reduced porosity. Combined with Apex's proprietary motorsport-specific forging blanks, this wheel offers exceptional brake clearance, optimized stiffness, deeper concavity, and the confidence needed for serious performance driving.

Built From True Motorsport Forgings
The SM-10RS begins as a forging weighing up to 120 pounds before machining. The immense pressure used during the forging process improves material density and eliminates porosity, creating an exceptionally strong foundation. Unlike generic third-party wheel blanks, Apex developed proprietary motorsport-specific forgings that provide complete control over brake clearance, spoke profiles, concavity, and overall structural performance.
Using extensive Finite Element Analysis (FEA), Apex engineers optimized every area of the wheel to remove unnecessary material while reinforcing critical stress zones. The result is a wheel that remains exceptionally lightweight without sacrificing durability or load capacity.
Advanced I-Beam Spoke Technology
The SM-10RS features Apex's signature side-milled I-beam spoke design. Material is precision-machined from both sides of each spoke using CNC equipment, reducing weight while maintaining exceptional rigidity. This advanced manufacturing process allows Apex to maximize stiffness and responsiveness without unnecessary mass.
The result is a wheel that offers nearly identical weight to the VS-5RS while delivering almost 10% greater stiffness and approximately 25% greater stiffness than Apex's first-generation forged wheel designs.
Engineered for Abuse
The SM-10RS was designed to withstand the demands of performance driving. A reinforced Sprint Spec inner lip improves impact resistance, while paintless knurled bead seats help prevent tire movement under aggressive acceleration and braking. Massive brake clearance, application-specific spoke profiles, deep concavity capability, and compatibility with oversized race hardware further reinforce the wheel's motorsport pedigree.
To validate durability, Apex utilizes independent testing through STL in Ohio, where Sprint Line wheels are evaluated beyond traditional JWL standards using increased loads, extended testing durations, and more severe impact procedures.
