Apex SM-10RS 19x10.5 Forged Wheel - 5x130 BP / ET44 / 71.6mm CB - Motorsport Gold (SM10RS19105ET44-5130-716-MGD)
The Apex SM-10RS was engineered for drivers who refuse to compromise between lightweight performance, structural strength, and race-ready durability. As a flagship member of Apex's Sprint Line, the SM-10RS utilizes advanced forged construction, motorsport-derived engineering, and extensive real-world testing to create a wheel capable of handling demanding street and track environments alike.
Built from a proprietary 6061-T6 aluminum forging compressed under an immense 10,000 metric tons of pressure, the SM-10RS delivers exceptional strength through improved grain structure and reduced material porosity. Combined with Apex's motorsport-specific forging blanks and extensive Finite Element Analysis, the result is a wheel that remains remarkably lightweight while offering the strength, stiffness, and durability enthusiasts expect from a premium forged wheel.

Purpose-Built Motorsport Forgings
Unlike manufacturers that rely on generic third-party forgings, Apex developed proprietary motorsport-specific blanks to maximize wheel performance. This allows complete control over spoke design, brake clearance, wheel concavity, and structural optimization. The result is a forging specifically engineered for high-performance driving applications rather than adapted from a generic wheel platform.
Each forging begins as a blank weighing up to 120 pounds before precision machining. The extreme pressure used during manufacturing improves aluminum density and grain structure while minimizing porosity, creating an exceptionally strong foundation.
Advanced I-Beam Spoke Engineering
The SM-10RS features Apex's signature side-milled I-beam spoke design. Material is strategically removed from both sides of each spoke using precision CNC machining to reduce weight while maintaining exceptional rigidity. This process creates a stronger, lighter wheel that enhances steering response, handling precision, and overall driving confidence.
Through advanced spoke optimization and FEA-guided development, the SM-10RS achieves nearly 10% greater stiffness than the VS-5RS while remaining nearly identical in weight. Compared to Apex's first-generation forged wheels, stiffness improvements approach 25%.
Track-Tested Strength and Durability
The reinforced Sprint Spec inner lip utilizes a unique channel profile that improves impact resistance while preserving lightweight performance characteristics. Paintless knurled bead seats maximize tire retention under repeated hard braking and acceleration, helping maintain wheel balance and reducing tire movement.
Independent testing conducted by STL in Ohio subjects Sprint Line wheels to standards beyond traditional JWL requirements, including increased testing loads, extended testing durations, and more severe impact testing procedures.
