Apex SM-10RS 18x9 Forged Wheel - 5x114.3 BP / ET23 / 60.1mm CB - Satin Black (SM10RS189ET23-51143-601-NSBK)
The Apex SM-10RS is engineered for enthusiasts who expect more from their wheels than just great looks. As part of Apex's Sprint Line of forged wheels, the SM-10RS combines lightweight construction, exceptional stiffness, and race-proven durability into a package designed to perform under the most demanding driving conditions.
Manufactured from a massive 6061-T6 aluminum forging formed under an incredible 10,000 metric tons of pressure, the SM-10RS benefits from improved grain structure and reduced porosity for outstanding strength. Combined with Apex's proprietary motorsport-specific forging blanks, this wheel delivers exceptional brake clearance, optimized spoke geometry, and the durability serious drivers demand from a premium forged wheel.

Purpose-Built for Performance
The SM-10RS begins life as a forging weighing up to 120 pounds before machining. The immense pressure used during the forging process refines the aluminum's grain structure while eliminating porosity, creating an exceptionally strong foundation. Unlike many wheel manufacturers that rely on generic third-party blanks, Apex designed proprietary motorsport-specific forgings to maximize brake clearance, spoke geometry flexibility, and overall wheel performance.
Extensive Finite Element Analysis (FEA) was utilized throughout development to reinforce high-load areas while eliminating unnecessary material. This process results in a wheel that is exceptionally lightweight without sacrificing structural integrity or long-term durability.
Advanced I-Beam Spoke Technology
One of the defining characteristics of the SM-10RS is its advanced side-milled I-beam spoke design. Material is precisely machined from both sides of each spoke using CNC equipment, reducing weight while maintaining exceptional rigidity. This sophisticated manufacturing process allows Apex to maximize stiffness and responsiveness without adding unnecessary mass.
The result is a wheel that delivers nearly identical weight to the popular VS-5RS while offering almost 10% greater stiffness and approximately 25% greater stiffness than Apex's first-generation forged wheel designs.
Built to Handle Abuse
The SM-10RS was designed to thrive in demanding environments. The reinforced Sprint Spec inner lip enhances impact resistance, while paintless knurled bead seats help prevent tire slippage under hard braking and acceleration. Massive brake clearance, deep concavity capability, and compatibility with oversized race hardware further reinforce the wheel's motorsport-focused design.
To validate durability, Apex utilizes independent testing through STL in Ohio, where Sprint Line wheels are evaluated beyond traditional JWL standards using increased loads, more severe impact testing, and longer testing durations.
