Apex SM-10RS 18x9.5 Forged Wheel - 5x112 BP / ET41 / 57.1mm CB - Satin Bronze (SM10RS1895ET41-5112-571-NSBZ)
The Apex SM-10RS was engineered for enthusiasts who demand maximum performance without compromise. 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 excel on the street, at the track, and anywhere performance matters.
Manufactured from a massive 6061-T6 aluminum forging using an incredible 10,000 metric tons of pressure, the SM-10RS delivers outstanding strength through improved grain structure and reduced porosity. Apex's proprietary motorsport-specific forging blanks provide the freedom to optimize brake clearance, concavity, spoke geometry, and overall performance, creating a wheel that is exceptionally light while remaining incredibly strong.

Forged for Serious Performance
The SM-10RS starts life as a forging weighing up to 120 pounds before machining. The immense pressure used during the forging process improves material density and strength, creating the ideal foundation for a high-performance wheel. Unlike generic third-party forgings, Apex designed its own motorsport-specific blanks from the ground up, allowing complete control over critical design elements and fitment characteristics.
Extensive Finite Element Analysis was utilized throughout development to reinforce high-stress areas while removing unnecessary material. The result is a wheel that remains exceptionally lightweight without sacrificing durability or load capacity.
Advanced I-Beam Spoke Design
One of the defining features of the SM-10RS is its side-milled I-beam spoke architecture. Material is precisely removed from both sides of each spoke using CNC machining, reducing weight while maintaining structural integrity. This advanced 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.
Engineered Beyond Industry Standards
Apex developed the SM-10RS to withstand the demands of aggressive driving and motorsport use. A reinforced Sprint Spec inner lip increases impact resistance, while paintless knurled bead seats help prevent tire slippage during hard acceleration and braking. Massive brake clearance, application-specific spoke profiles, and compatibility with oversized race hardware further enhance the wheel's track-ready capabilities.
To validate performance, Apex partners with STL, an independent testing laboratory in Ohio, where Sprint Line wheels are tested beyond traditional JWL standards using increased loads, greater impact severity, and extended testing cycles.
