Apex SM-10RS 19x11 Forged Wheel - 5x120.65 BP / ET38 / 70.3mm CB - Satin Bronze (SM10RS1911ET38-512065-703-NSBZ)
The Apex SM-10RS represents the next evolution of lightweight forged wheel performance. Designed as part of Apex's Sprint Line, the SM-10RS blends advanced engineering, motorsport-focused durability, and aggressive styling into a wheel that delivers exceptional strength, stiffness, and brake clearance without carrying unnecessary weight. Whether you're chasing lap times or upgrading your street-driven performance vehicle, the SM-10RS was engineered to perform under pressure.
Constructed from forged 6061-T6 aluminum and manufactured using a massive 10,000 metric ton forging process, each wheel begins as a forging weighing up to 120 pounds before extensive CNC machining transforms it into a highly optimized performance wheel. Apex engineers utilized extensive Finite Element Analysis to reinforce high-stress areas while removing unnecessary material, creating a wheel that is remarkably lightweight without sacrificing durability.

Forged for Maximum Performance
The SM-10RS starts with a purpose-built forging formed under 10,000 metric tons of pressure. This manufacturing process improves aluminum grain structure and reduces porosity, creating an exceptionally strong foundation that supports aggressive driving conditions while remaining lightweight.
I-Beam Spoke Technology
Precision CNC side milling removes unnecessary material from both sides of each spoke, creating an advanced I-beam profile. This design reduces weight while preserving the strength and stiffness required for demanding street and track use.
Sprint Spec Inner Lip
Apex reinforced critical impact zones by incorporating its Sprint spec inner lip design. This unique profile improves durability and impact resistance while maintaining the low weight characteristics that define the Sprint Line.
Independent Testing and Validation
The SM-10RS is independently tested by STL to standards that exceed typical JWL requirements. Increased testing loads, extended durations, and more demanding impact testing provide additional confidence for enthusiasts who push their equipment to the limit.
Fitment
- Applications Utilizing 5x120.65 Bolt Pattern and 70.3mm Center Bore
- Verify Brake Clearance, Suspension Clearance, Fender Clearance, and Tire Fitment Prior to Installation
FAQs
Why does the SM-10RS use a Sprint spec inner lip?
The Sprint spec inner lip was engineered to improve durability and impact resistance in critical areas while maintaining the lightweight performance characteristics of the wheel.
Will this wheel accept OEM TPMS sensors?
Yes. The SM-10RS is compatible with both OEM and aftermarket TPMS sensors and accepts standard valve stems.
