Apex EC-7RS 18x12 Forged Wheel (EC7RS1812ET41-5120-671-AN) - Chevrolet
The Apex EC-7RS is the most advanced and lightweight version of the iconic EC-7 wheel design. Developed as part of Apex's Sprint Line of forged wheels, the EC-7RS was engineered to maximize performance through reduced weight, increased strength, and race-proven durability. Finished in Anthracite, this fully forged wheel delivers the ideal combination of aggressive styling, motorsport capability, and uncompromising engineering.
Built from proprietary motorsport-specific forged blanks, the EC-7RS incorporates extensive side milling, advanced structural optimization, a reinforced Sprint Spec inner lip, and independent third-party validation. The result is a wheel designed to withstand the rigors of track driving while remaining exceptionally lightweight and responsive.

Purpose-Built Forged Performance
Unlike many forged wheels that utilize generic third-party blanks, the EC-7RS starts with Apex-developed motorsport forgings. These proprietary blanks allow complete control over spoke design, brake clearance, concavity, and structural strength, resulting in a wheel engineered specifically for high-performance applications.
10,000 Tons of Forging Pressure
Each EC-7RS begins as a forged aluminum blank weighing up to 120 pounds before machining. Formed under 10,000 metric tons of pressure, the forging process improves material density and grain structure while eliminating porosity. This creates an exceptionally strong foundation capable of handling demanding street and track environments.
Advanced Side-Milled Spoke Design
One of the defining characteristics of the EC-7RS is its aggressive side-milled spoke design. Precision CNC machining removes excess material from low-stress areas, reducing overall wheel weight while maintaining exceptional structural integrity. The result is quicker acceleration, sharper handling response, and reduced unsprung mass.
Sprint Spec Inner Lip Technology
Apex engineers strategically reinforced key load-bearing areas after removing every unnecessary ounce of material. The Sprint Spec inner lip features a unique channel profile that improves impact resistance and durability, creating a wheel that remains lightweight without compromising strength.
Independently Tested for Confidence
The EC-7RS undergoes extensive third-party validation through STL, an independent testing laboratory. Testing exceeds traditional JWL requirements through increased impact severity, greater loads, and extended durability cycles to ensure dependable performance under extreme conditions.
Engineered for Big Brake Systems
Through years of development and extensive 3D laser scanning, Apex created a high-clearance barrel profile and vehicle-specific spoke geometry capable of accommodating many factory and aftermarket big brake packages. The result is exceptional brake clearance without sacrificing wheel strength or appearance.
Track-Ready Details
Paintless knurled bead seats help prevent tire slippage during hard acceleration and braking, while oversized lug openings make wheel changes easier with impact tools. Laser-engraved wheel specifications remain easy to locate and read throughout the life of the wheel.
Fitment
