Engineered for Competitive Driving
Unlike generic forged wheels produced from third-party blanks, the EC-7RS utilizes proprietary Apex-designed motorsport forgings. This allows complete control over spoke geometry, brake clearance, concavity, and structural integrity, resulting in a wheel purpose-built for serious performance driving.
10K Ton Forged Strength
Each EC-7RS begins as a forged aluminum blank weighing up to 120 pounds before machining. Produced under an incredible 10,000 metric tons of pressure, the forging process improves material density, strengthens grain structure, and eliminates porosity to create an exceptionally durable foundation.
Advanced Side-Milled Design
One of the most significant upgrades found on the EC-7RS is its aggressive side-milled spoke architecture. Precision CNC machining removes unnecessary material while preserving structural strength, helping achieve exceptional weight savings without compromising durability.
Sprint Spec Inner Lip Technology
Apex reinforced key load-bearing areas with its innovative Sprint Spec inner lip design. This unique profile increases impact resistance and load capacity while maintaining the lightweight characteristics essential for track-focused performance.
Independent Testing Beyond Standards
Every Sprint Line wheel undergoes independent testing through STL in Ohio. Testing exceeds standard JWL requirements through increased loads, greater impact severity, and longer testing durations to validate real-world durability and reliability.
Massive Brake Clearance
Using advanced 3D laser scans of factory and aftermarket braking systems, Apex developed application-specific spoke profiles and a high-clearance barrel design. The result is exceptional brake clearance without sacrificing strength, concavity, or low weight.
Track-Ready Details
Paintless knurled bead seats help minimize tire slippage during hard acceleration and braking. Oversized lug pockets accommodate race hardware and impact sockets, while laser-engraved specifications provide quick identification during maintenance and trackside wheel changes.
