Apex SM-10RS 19x12.5 Forged Wheel - 5x120.65 BP / ET55 / 70.3mm CB - Satin Bronze (SM10RS19125ET55-512065-703-NSBZ)
The Apex SM-10RS is built for serious enthusiasts who want forged strength, low weight, and real track-ready durability without compromise. As part of Apex's Sprint Line, this 19x12.5 Satin Bronze SM-10RS combines aggressive sizing with advanced motorsport engineering, making it a strong choice for high-performance applications that demand stiffness, brake clearance, and confidence under load.
Each SM-10RS begins as a forged 6061-T6 aluminum blank formed under 10,000 metric tons of pressure. This process improves grain structure, reduces porosity, and creates a stronger foundation before precision machining removes unnecessary material. Apex then uses extensive Finite Element Analysis to reinforce critical areas while keeping weight low, resulting in a wheel engineered for demanding street and track use.

Forged Sprint Line Engineering
The SM-10RS uses Apex's proprietary Sprint Line forging approach to create a wheel that is light without being fragile. Critical areas are reinforced where strength matters most, while unnecessary material is removed to keep rotational weight down.
I-Beam Spoke Technology
Precision side milling creates an I-beam effect on each spoke, removing excess material that does not contribute to strength. This helps the SM-10RS deliver the stiffness and response serious drivers expect from a premium forged wheel.
Track-Ready Details
The SM-10RS includes a reinforced inner lip, paintless knurled bead seats, laser-engraved specifications, and clearance for oversized race lugs and impact sockets. These details are built for enthusiasts who use their wheels hard and need them to perform consistently.
Fitment
- Applications Utilizing 5x120.65 Bolt Pattern and 70.3mm Center Bore
- Verify Brake Clearance, Suspension Clearance, Fender Clearance, Tire Size, and Vehicle Compatibility Prior to Installation
