Apex SM-10RS 18x9 Forged Wheel - 5x120 BP / ET30 / 72.56mm CB - Satin Black (SM10RS189ET30-5120-7256-NSBK)
The Apex SM-10RS is engineered for enthusiasts who refuse to compromise between weight, strength, and performance. As part of Apex's Sprint Line of forged wheels, the SM-10RS delivers race-bred technology, exceptional stiffness, and lightweight construction in a package designed to excel on both the street and the track.
Manufactured from a massive 6061-T6 aluminum forging subjected to 10,000 metric tons of pressure, the SM-10RS benefits from improved grain structure and reduced porosity for outstanding strength and durability. Combined with Apex's proprietary motorsport-specific forging blanks, this wheel offers exceptional brake clearance, optimized spoke geometry, and the confidence required for demanding performance applications.

Motorsport Forged Technology
The SM-10RS starts as a forging weighing up to 120 pounds before machining. The immense pressure used during the forging process improves material density while eliminating porosity, resulting in exceptional strength and structural integrity. Unlike manufacturers that utilize generic third-party blanks, Apex developed proprietary motorsport-specific forgings to maximize brake clearance, concavity, spoke design flexibility, and overall performance.
Using extensive Finite Element Analysis (FEA), Apex engineers strategically reinforced high-stress areas while removing material that offered no measurable strength benefit. This process creates a wheel that remains exceptionally lightweight without compromising durability.
Advanced I-Beam Spoke Design
One of the SM-10RS's defining characteristics is its side-milled I-beam spoke architecture. Material is precision-machined from both sides of each spoke using CNC equipment, reducing weight while maintaining outstanding rigidity. This advanced design allows Apex to maximize stiffness and responsiveness without adding unnecessary mass.
The result is a wheel that is nearly identical in weight to the VS-5RS while providing almost 10% greater stiffness and approximately 25% greater stiffness than Apex's first-generation forged wheel designs.
Engineered for Serious Driving
The SM-10RS was developed to withstand the rigors 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, deep concavity capability, application-specific spoke profiles, and compatibility with oversized race hardware further enhance the wheel's performance-focused design.
To validate durability, Apex utilizes independent testing through STL in Ohio. Sprint Line wheels are tested beyond traditional JWL standards with increased loads, longer testing durations, and more severe impact testing procedures.
