Apex SM-10RS 19x12 Forged Wheel - Satin Black (SM10RS1912ET57-51143-705-NSBK)
If you're looking for a forged wheel that delivers uncompromising performance without sacrificing durability, the Apex SM-10RS is built for exactly that purpose. As part of Apex's Sprint Line, the SM-10RS combines cutting-edge forging technology, advanced engineering analysis, and motorsport-focused design to create a wheel that is exceptionally lightweight while remaining incredibly strong. Finished in Satin Black, this 19x12 wheel offers an aggressive appearance backed by race-proven engineering that performs on the street, at the track, and everywhere in between.
Unlike many wheels that prioritize weight reduction at the expense of strength, the SM-10RS was developed to optimize both. Through extensive computer modeling, proprietary forging blanks, and strategic reinforcement of critical load-bearing areas, Apex created a wheel that offers outstanding stiffness, impressive impact resistance, and reduced rotational mass. The result is a wheel that enhances vehicle responsiveness while providing the durability enthusiasts demand.
10K Tons of Pressure
The foundation of every SM-10RS starts with a massive forged aluminum blank weighing as much as 120 pounds before machining. Apex utilizes specialized equipment capable of applying 10,000 metric tons of pressure during the forging process. This immense force improves the aluminum's grain structure while minimizing porosity, creating a stronger and more durable wheel before any machining even begins.
True Motorsport Blanks
Many wheel manufacturers rely on third-party forging blanks originally designed for general street applications. Apex takes a different approach by engineering proprietary motorsport-specific forging blanks from the ground up. This allows complete control over wheel dimensions, spoke geometry, brake clearance, concavity profiles, and structural integrity. The result is a wheel optimized specifically for high-performance driving rather than compromised by limitations of off-the-shelf forgings.
I-Beam Spoke Technology
One of the defining characteristics of the SM-10RS is its advanced side-milled spoke design. Material is precisely removed from both sides of each spoke using CNC ball-cut machining, creating an I-beam profile that maximizes strength while minimizing weight. This process removes unnecessary mass from low-stress areas while preserving structural rigidity where it's needed most. While often considered too costly for many manufacturers, Apex views this design as essential for maximizing performance.
A Stronger Lightweight Wheel
Lightweight wheels often sacrifice durability in pursuit of lower weight figures. Apex took a different path with the Sprint Line. Engineers first removed as much material as possible through extensive optimization, then strategically added material back into key load-bearing areas. This approach resulted in a stronger inner lip design, higher load capacity, and increased durability without giving up the lightweight performance enthusiasts expect from a forged wheel.
Weight Optimized Engineering
The SM-10RS benefits from extensive Finite Element Analysis (FEA) during development. This advanced engineering process allowed Apex to identify high-stress regions requiring reinforcement while simultaneously eliminating material from areas that contributed little to overall strength. The result is an exceptionally lightweight wheel that avoids the structural compromises often associated with aggressive weight reduction.
Greater Stiffness for Improved Performance
Wheel stiffness plays a significant role in vehicle responsiveness and handling precision. Apex utilized advanced bending load simulations to refine spoke geometry and increase overall rigidity. The result is a wheel that delivers nearly 10 percent greater stiffness than the Apex VS-5RS while maintaining nearly identical weight. Compared to Apex's first-generation forged wheels, stiffness improvements approach 25 percent, helping drivers achieve more consistent performance and feedback.
Independently Tested Beyond Industry Standards
Apex believes performance claims should be validated through independent testing rather than relying solely on internal evaluations. The SM-10RS was tested by STL, an independent laboratory in Ohio, using standards that exceed traditional JWL testing requirements. Increased testing duration, greater impact drop heights, and higher applied loads help ensure the wheel performs under demanding real-world conditions.
Sprint Spec Inner Lip
The Sprint spec inner lip incorporates a unique reinforced channel profile that significantly increases durability and impact resistance. Despite being lighter than many comparable flow-formed wheels, the SM-10RS features an inner lip that is actually stronger than previous Apex designs, providing additional confidence during aggressive driving and track use.
Massive Brake Clearance
Brake clearance has always been a priority for Apex. The SM-10RS incorporates a high-clearance barrel design and application-specific spoke profiles developed using years of brake fitment experience. This design philosophy helps accommodate large factory and aftermarket brake systems commonly found on modern performance vehicles.
Deeper Concavity
Apex redesigned its forging profiles to allow significantly deeper concave spoke designs. By utilizing detailed 3D laser scans of both factory and aftermarket brake systems, Apex can optimize wheel profiles for specific applications while maximizing both aesthetics and clearance. The result is a more aggressive appearance without sacrificing functionality.
Paintless Knurled Bead Technology
Repeated acceleration and heavy braking can cause tire movement along the wheel's bead seat, potentially leading to balance issues and vibration. The SM-10RS utilizes paintless knurled bead seats that remain sharp and effective over time, helping maintain tire grip on the wheel surface and reducing the likelihood of tire slippage under demanding conditions.
Built for Impact Sockets
Track enthusiasts need wheels that work seamlessly with professional-grade tools. The SM-10RS is engineered to accommodate oversized race lugs and impact sockets, eliminating the need for fragile tuner-style hardware and allowing for faster wheel changes during track events and maintenance.
Laser-Engraved Specifications
Instead of difficult-to-read stamped markings, Apex laser engraves wheel specifications directly onto the barrel in a highly visible location. This makes wheel identification quick and easy whether you're rotating tires, checking fitment details, or servicing your vehicle.
Hub Centric Design
The SM-10RS is engineered for application-specific fitment and utilizes hub-centric designs whenever possible. This minimizes the need for centering rings while promoting proper wheel alignment and vibration-free operation.
Center Cap Compatibility
Most SM-10RS applications include a gloss black Apex center cap. Many configurations also support compatible OEM center caps, providing additional customization options depending on the application. Certain specialized fitments may utilize unique cap configurations or capless center sections.
Wheel Hardware Compatibility
Apex designs its wheels to work with OEM mounting hardware whenever possible while also supporting high-quality wheel spacers, wheel locks, stud conversion kits, and other performance hardware. Hardware requirements may vary by application, so compatibility should always be verified prior to installation.
TPMS Ready
The SM-10RS accepts OEM and aftermarket tire pressure monitoring sensors and standard valve stems. Drivers without TPMS sensors can also utilize compatible metal valve stems available in multiple finishes.
