Forged Under Extreme 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 aluminum grain structure, increases material density, and reduces porosity. This creates an exceptionally strong foundation capable of handling the demands of aggressive street driving, track days, and competitive motorsport environments.
Purpose-Built Motorsport Forgings
Unlike many forged wheels that rely on generic third-party blanks, Apex engineered proprietary forging profiles specifically for motorsport applications. This allows complete control over spoke geometry, wheel concavity, brake clearance, and structural integrity, resulting in a wheel optimized for maximum performance and durability.
Advanced Side-Milled Spoke Technology
One of the defining upgrades found on the EC-7RS is its aggressive side-milled spoke architecture. Precision CNC machining removes excess material that does not contribute to structural strength, reducing rotational weight while maintaining critical load-bearing integrity. The result is sharper handling, improved responsiveness, and enhanced overall vehicle performance.
Lightweight Without Compromise
Many lightweight wheels sacrifice durability in pursuit of lower weight. Apex followed a different philosophy by strategically removing unnecessary material and then 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 durability and performance, Apex utilizes independent testing through STL in Ohio. Sprint Line wheels undergo testing beyond traditional JWL requirements with increased impact severity, higher load thresholds, and extended testing durations 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 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 developed with enthusiasts and racers in mind. Oversized socket clearance also simplifies wheel changes during track events and race weekends.
Fitment
