Forged for Maximum Strength
Every EC-7RS starts life as a forged aluminum blank weighing up to 120 pounds before machining. Using an incredible 10,000 metric tons of pressure during the forging process improves material density and grain structure while reducing porosity. This creates an exceptionally strong foundation capable of handling the demands of high-performance driving and competitive motorsport use.
True Motorsport Engineering
Unlike many forged wheels built around generic third-party blanks, Apex developed 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 purpose-built for maximum performance.
Advanced Side-Milled Spoke Technology
One of the most significant upgrades found on the EC-7RS is its side-milled spoke design. Precision CNC machining removes excess material that does not contribute to strength, reducing rotational weight while maintaining critical structural integrity. The result is improved responsiveness and sharper vehicle dynamics.
Lightweight Without Compromise
Many lightweight wheels achieve lower weight by sacrificing durability. 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 increased 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 are tested beyond traditional JWL requirements through increased impact severity, extended 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 weight.
Track-Ready Features Throughout
From paintless knurled bead seats that maximize tire grip to laser-engraved specifications that remain easy to read over time, every detail of the EC-7RS was designed with enthusiasts and racers in mind. Oversized socket clearance simplifies wheel changes during track days and race weekends.
Fitment
- Chevrolet Applications Utilizing 5x120.65 Bolt Pattern and 70.3mm Center Bore
- Verify Brake Clearance, Suspension Clearance, and Tire Fitment Prior to Installation
FAQs
What makes the EC-7RS different from the standard EC-7?
The EC-7RS is a fully forged Sprint Line wheel featuring side-milled spokes, proprietary forged blanks, a reinforced Sprint Spec inner lip, advanced weight optimization, and increased durability compared to the flow-formed EC-7.
Can I use factory TPMS sensors and OEM wheel hardware?
Yes. The EC-7RS is compatible with OEM and aftermarket TPMS sensors, factory mounting hardware, wheel locks, stud conversion kits, and most wheel spacer configurations.
