Apex SM-10RS 19x9.5 Forged Wheel - Motorsport Gold (SM10RS1995ET25-5112-666-MGD)
The Apex SM-10RS represents the pinnacle of lightweight forged wheel technology, combining advanced engineering, race-proven durability, and aggressive motorsport styling into one uncompromising package. As a member of Apex's Sprint Line, the SM-10RS was developed for enthusiasts who demand maximum performance without sacrificing strength. Finished in striking Motorsport Gold, this 19x9.5 forged wheel delivers exceptional visual impact while providing the stiffness, brake clearance, and durability needed for serious street and track use.
Built from proprietary 10K-ton forged 6061-T6 aluminum blanks, the SM-10RS was engineered to push the limits of lightweight wheel design. Through extensive Finite Element Analysis, independent third-party testing, and innovative spoke architecture, Apex created a wheel that remains remarkably light while offering exceptional structural integrity. The result is improved acceleration, sharper handling response, enhanced steering feedback, and the confidence to perform under the harshest driving conditions.
10K Tons of Forging Pressure
Every SM-10RS begins as a massive forged aluminum blank weighing up to 120 pounds before machining. Apex utilizes specialized forging equipment capable of exerting 10,000 metric tons of pressure during production. This extreme force improves the aluminum's grain structure while minimizing porosity, creating a stronger foundation that allows engineers to remove unnecessary material without compromising durability.
True Motorsport Forging Blanks
Unlike manufacturers that utilize generic third-party forgings, Apex developed proprietary motorsport-specific forging blanks from the ground up. This gives engineers complete control over spoke geometry, wheel dimensions, brake clearance, concavity profiles, and structural characteristics. By eliminating the limitations associated with off-the-shelf forgings, Apex can optimize every aspect of the wheel for high-performance applications.
I-Beam Spoke Technology
The signature feature of the SM-10RS is its side-milled spoke design. Precision CNC machining removes excess material from both sides of each spoke, creating an I-beam profile that maximizes structural efficiency. This process reduces weight while preserving strength in critical load-bearing areas, resulting in improved responsiveness and reduced rotational mass without sacrificing durability.
A Stronger Lightweight Wheel
Many lightweight wheels achieve their low weight by removing material wherever possible, often compromising long-term durability. Apex took a more calculated approach. Engineers first optimized the wheel by eliminating unnecessary mass and then strategically reinforced critical stress areas by adding material back where it mattered most. The result is a stronger inner lip, increased load capacity, and improved impact resistance while maintaining exceptional weight savings.
Weight Optimized Through FEA
Extensive Finite Element Analysis was used throughout development to identify stress concentrations and optimize material placement. High-load areas were reinforced while material was removed from regions that provided little structural benefit. This advanced engineering process allowed Apex to create a wheel that is exceptionally lightweight without introducing the compromises commonly associated with aggressive weight reduction.
Greater Stiffness and Enhanced Feedback
Wheel stiffness has a direct impact on steering precision, driver confidence, and handling performance. Through advanced bending-load simulations and spoke optimization, Apex increased rigidity without increasing wheel weight. The SM-10RS is nearly identical in weight to the VS-5RS while delivering nearly 10 percent greater stiffness and approximately 25 percent greater stiffness than Apex's first-generation forged wheels.
Independently Tested Beyond JWL Standards
Apex believes wheel performance should be verified through independent testing rather than relying solely on internal evaluations. The SM-10RS was tested by STL, an independent laboratory in Ohio, using procedures that exceed standard JWL requirements. Increased testing duration, higher impact drop heights, and greater load capacities help validate durability under real-world performance conditions.
Sprint Spec Reinforced Inner Lip
The SM-10RS incorporates Apex's Sprint spec inner lip design, featuring a reinforced channel profile engineered for greater impact resistance. Despite being lighter than many comparable flow-formed wheels, the reinforced inner lip provides exceptional durability and strength when encountering potholes, curbing, and demanding track environments.
Massive Brake Clearance
Brake clearance has been a priority for Apex since day one. The SM-10RS utilizes a high-clearance barrel profile and application-specific spoke geometry developed using advanced 3D laser scanning technology. This design helps accommodate many large factory and aftermarket brake systems without sacrificing wheel strength or aesthetics.
Deep Concavity
Apex redesigned its forging architecture to support deeper concave wheel faces while maintaining critical brake clearance. Detailed 3D scans of factory and aftermarket brake systems allow engineers to optimize each wheel profile for its intended application, resulting in a more aggressive appearance without compromising functionality.
Paintless Knurled Bead Seats
Repeated acceleration and heavy braking can cause tire movement along the wheel's bead seat. To combat this, the SM-10RS features paintless knurled bead seats that remain sharp and effective over time. Unlike painted knurling that can wear down, this design helps improve tire retention and reduce unwanted movement during aggressive driving.
Built for Impact Sockets
Track-focused enthusiasts need wheels that work seamlessly with professional-grade tools. The SM-10RS accommodates oversized race lugs and impact sockets, eliminating the need for delicate tuner-style hardware and making wheel changes faster and more convenient.
Laser-Engraved Specifications
Wheel specifications are laser engraved directly onto the barrel in a visible location, making wheel identification quick and easy during maintenance, wheel rotations, or trackside service.
Hub-Centric Engineering
All SM-10RS wheels are engineered as hub-centric applications whenever possible. This helps ensure proper wheel centering, reduces the need for centering rings, and contributes to smooth, vibration-free operation.
Center Cap Compatibility
Most SM-10RS wheels include a gloss black Apex center cap and many applications support compatible OEM center caps. Certain specialized applications may utilize unique cap configurations or capless center sections depending on fitment requirements.
Wheel Hardware Compatibility
Apex designs its wheels to work with OEM mounting hardware whenever possible while also supporting wheel spacers, wheel locks, stud conversion kits, and other performance accessories. Hardware requirements should always be verified before installation.
TPMS Compatible
The SM-10RS accepts OEM and aftermarket Tire Pressure Monitoring Sensors along with standard valve stems. Drivers seeking additional customization can also utilize optional metal valve stems available in multiple finishes.
