Apex EC-7RS 18x11 Forged Wheel (EC7RS1811ET38-512065-703-AN) - Chevrolet
Built for drivers who demand every possible performance advantage, the Apex EC-7RS takes the proven EC-7 design and elevates it into an ultralight forged wheel engineered for serious track and performance driving. As part of Apex's Sprint Line, the EC-7RS delivers reduced weight, increased strength, and race-proven durability to improve acceleration, braking, cornering response, and overall vehicle performance. Finished in Anthracite, this wheel combines aggressive styling with engineering designed to withstand the rigors of high-performance use.
Starting with proprietary forged blanks developed specifically for motorsport applications, the EC-7RS incorporates advanced side-milled spokes, extensive Finite Element Analysis optimization, a reinforced Sprint Spec inner lip, and independent third-party testing beyond industry standards. The result is an exceptionally lightweight forged wheel that maintains the strength and reliability required for demanding street and track environments.

Forged Under 10,000 Tons of Pressure
Every EC-7RS begins life as a forged aluminum blank weighing up to 120 pounds before machining. Formed using an incredible 10,000 metric tons of pressure, the forging process enhances grain structure, increases material density, and reduces porosity. This creates an exceptionally strong foundation capable of handling the demands of aggressive street driving, road course use, and competitive motorsport environments.
Purpose-Built Motorsport Engineering
Unlike many forged wheels that rely on generic third-party blanks, Apex developed proprietary forging profiles specifically for motorsport applications. This allows complete control over spoke geometry, brake clearance, concavity, and overall wheel strength, resulting in a wheel optimized for maximum performance.
Advanced Side-Milled Spoke Technology
One of the defining upgrades found on the EC-7RS is its aggressively side-milled spoke architecture. Precision CNC machining removes excess material that does not contribute to structural integrity, reducing rotational weight while maintaining critical strength. The result is improved responsiveness and sharper vehicle dynamics both on track and on the street.
Lightweight Without Sacrificing Durability
Many lightweight wheels achieve lower weight by compromising strength. Apex followed a different philosophy by removing unnecessary material and then strategically reinforcing critical stress areas. This process created a stronger Sprint Spec inner lip and improved load capacity while maintaining exceptionally low overall wheel weight.
Independently Tested Beyond Industry Standards
To validate performance and durability, Apex utilizes independent testing through STL in Ohio. Sprint Line wheels are tested beyond traditional JWL requirements through increased impact severity, longer testing durations, and higher load thresholds to ensure confidence under demanding real-world conditions.
Massive Brake Clearance
Developed using more than a decade of brake fitment experience and advanced 3D scanning technology, the EC-7RS incorporates a high-clearance barrel profile and application-specific spoke geometry. This design allows clearance for many large factory and aftermarket brake systems while maintaining optimal wheel strength and low weight.
Track-Ready Features Throughout
From paintless knurled bead seats that maximize tire grip to laser-engraved specifications that remain readable over time, every detail of the EC-7RS was designed with enthusiasts and racers in mind. Oversized socket clearance also simplifies wheel changes during track events and race weekends.
