Apex SM-10RS 18x9 Forged Wheel - 5x114.3 BP / ET23 / 60.1mm CB - Anthracite (SM10RS189ET23-51143-601-AN)
The Apex SM-10RS is built for enthusiasts who demand maximum performance from every component on their vehicle. As part of Apex's Sprint Line of forged wheels, the SM-10RS combines cutting-edge engineering, lightweight construction, and race-proven durability to create a wheel equally at home on the street, autocross course, or road circuit.
Constructed from a massive 6061-T6 aluminum forging formed under 10,000 metric tons of pressure, the SM-10RS delivers exceptional strength through improved grain structure and reduced porosity. Apex's proprietary motorsport-specific forging blanks allow complete control over brake clearance, spoke geometry, concavity, and overall wheel performance, resulting in a forged wheel engineered without compromise.

Forged Strength Meets Lightweight Performance
The SM-10RS begins as a forging weighing up to 120 pounds before any machining takes place. The extreme pressure used during the forging process enhances aluminum strength by improving grain structure and eliminating porosity. This creates the ideal foundation for a lightweight wheel capable of handling the demands of aggressive driving and motorsport competition.
Unlike many manufacturers that rely on generic third-party forgings, Apex developed its own motorsport-specific blanks from the ground up. This approach allows complete control over wheel architecture, brake clearance, spoke profiles, and overall structural integrity.
Advanced I-Beam Spoke Technology
One of the SM-10RS's most distinctive features is its side-milled I-beam spoke design. Material is precision-machined from both sides of each spoke using CNC equipment, removing excess weight while maintaining exceptional rigidity. This advanced machining process helps create 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 Through Extensive Analysis
Apex utilized comprehensive Finite Element Analysis throughout the development process to reinforce high-stress areas and remove material where it offered no measurable strength benefit. This optimization process creates a wheel that remains exceptionally lightweight without the durability compromises commonly found in other lightweight wheel designs.
The reinforced Sprint Spec inner lip further improves durability, while paintless knurled bead seats help reduce tire slippage under hard acceleration and braking. Combined with massive brake clearance, deep concavity capability, and compatibility with oversized race hardware, the SM-10RS is built for serious performance enthusiasts.
