Apex SM-10RS 19x12.5 Forged Wheel - 5x120.65 BP / ET55 / 70.3mm CB - Motorsport Gold (SM10RS19125ET55-512065-703-MGD)
The Apex SM-10RS delivers the ultimate combination of lightweight performance, motorsport durability, and cutting-edge forged wheel technology. Finished in a striking Motorsport Gold finish, this 19x12.5 wheel is engineered for enthusiasts who refuse to compromise between strength, stiffness, and weight. Whether you're chasing lap times at the track or building a serious street machine, the SM-10RS is designed to handle the demands of modern high-performance driving.
As part of Apex's Sprint Line forged wheel lineup, the SM-10RS begins as a proprietary 6061-T6 forged blank formed under an incredible 10,000 metric tons of pressure. This advanced manufacturing process improves grain structure and eliminates porosity, creating a stronger foundation before precision CNC machining removes every unnecessary gram. The result is a wheel that is exceptionally lightweight while maintaining the strength, stiffness, and durability required for aggressive driving environments.

Forged for Maximum Performance
The SM-10RS utilizes proprietary forged blanks engineered specifically for motorsport use. Unlike generic forgings that limit design flexibility, Apex developed its own blank profiles to maximize brake clearance, concavity, spoke design, and overall wheel performance.
Advanced I-Beam Spoke Design
Each spoke features extensive side milling to create Apex's signature I-beam profile. Material that does not contribute to strength is carefully removed through precision CNC machining, reducing weight while preserving structural integrity and stiffness.
Sprint Spec Reinforced Inner Lip
The SM-10RS features Apex's strengthened Sprint spec inner lip design. This unique channel profile provides greater durability and impact resistance, delivering confidence during hard track use and demanding road conditions.
Independent Testing and Validation
Apex believes performance claims should be verified. The SM-10RS underwent independent testing through STL, exceeding standard JWL requirements with increased load testing, greater impact severity, and extended durability cycles.
Fitment
- Applications Utilizing 5x120.65 Bolt Pattern and 70.3mm Center Bore
- Verify Brake Clearance, Suspension Clearance, Fender Clearance, Tire Size, and Overall Vehicle Compatibility Prior to Installation
FAQs
What makes the SM-10RS different from a conventional forged wheel?
