Motorsport Forged Performance
Unlike many forged wheels that utilize generic third-party blanks, the EC-7RS begins with proprietary Apex-developed motorsport forgings. This allows engineers complete control over spoke geometry, brake clearance, concavity profiles, and structural strength, resulting in a wheel purpose-built for high-performance applications.
10,000 Tons of Forging Force
Each EC-7RS starts as a forged aluminum blank weighing up to 120 pounds before machining. Formed under 10,000 metric tons of pressure, the forging process significantly improves aluminum density and grain structure while eliminating porosity. The result is an exceptionally strong foundation capable of handling the demands of competitive driving.
Advanced Side-Milled Spoke Design
One of the most significant upgrades found on the EC-7RS is its extensive side-milled spoke design. Precision CNC machining removes unnecessary material from low-stress areas while maintaining structural integrity. This reduces rotational mass and contributes to sharper handling, quicker acceleration, and improved braking response.
Sprint Spec Inner Lip Technology
After removing every unnecessary ounce of material, Apex strategically reinforced key load-bearing areas. The Sprint Spec inner lip features a unique channel profile that increases durability and impact resistance, helping the wheel withstand demanding track conditions without compromising performance.
Independently Tested Beyond Industry Standards
The EC-7RS undergoes extensive third-party testing through STL, an independent testing laboratory. Testing exceeds standard JWL requirements through increased loads, higher impact severity, and longer testing durations, providing additional confidence for enthusiasts who push their vehicles to the limit.
Exceptional Brake Clearance
Utilizing advanced 3D laser scanning and more than a decade of brake fitment development, Apex engineered the EC-7RS with exceptional brake clearance. A high-clearance barrel profile and application-specific spoke geometry allow compatibility with many factory and aftermarket big brake systems.
Track-Ready Details
Paintless knurled bead seats help prevent tire slippage during hard acceleration and braking, while oversized lug openings accommodate race hardware and impact sockets for fast wheel changes. Laser-engraved wheel specifications remain easy to locate and read throughout the life of the wheel.
Fitment
- Chevrolet Applications Utilizing 5x120 Bolt Pattern and 67.1mm Center Bore
- Verify Brake Clearance, Suspension Clearance, and Tire Fitment Prior to Installation
FAQs
