Flow-Formed Performance Engineering
The EC-7 utilizes Apex's advanced flow forming process to improve the grain structure and mechanical properties of the wheel barrel. This manufacturing method increases strength and rigidity while allowing engineers to reduce excess material, resulting in a lightweight wheel that delivers outstanding durability and performance.
Extensive Finite Element Analysis was used throughout development to reinforce critical load areas while removing material where it provided no structural benefit. The result is a wheel optimized for strength-to-weight efficiency and long-term reliability.
Engineered for Massive Brake Clearance
Large brake systems often require larger and heavier wheel combinations, but the EC-7 was specifically engineered to maximize brake clearance while maintaining lightweight 18 inch sizing. Through comprehensive laser scanning and extensive fitment testing, Apex developed the EC-7 to clear many high-performance brake systems that frequently require larger diameter wheels from competing designs.
Aggressive Concavity and Timeless Styling
The EC-7 utilizes multiple concave face profiles to maximize brake clearance and visual depth across a wide range of applications. The aggressive concave profile creates a purposeful motorsport appearance while contributing to reduced wheel weight. Finished in Anthracite, the EC-7 delivers a clean, aggressive look that perfectly complements Corvette styling.
Built for Track Use
Track enthusiasts will appreciate the EC-7's ability to accommodate oversized race lugs and impact sockets. Unlike many lightweight wheel designs that require specialized tuner hardware, the EC-7 was engineered with real-world track serviceability in mind.
The wheel receives a multi-stage liquid paint finish over a powder coated base coat for long-term durability. Apex also leaves the mounting pad, center bore, and lug holes free from excess coating material to help ensure proper fitment and accurate torque values.
Certified Strength and OEM Compatibility
All Apex Flow Formed wheels meet or exceed JWL load rating requirements and are independently certified through VIA testing standards. Apex provides legitimate VIA registration numbers to verify compliance and structural integrity.
The EC-7 is compatible with OEM and aftermarket TPMS sensors, factory hardware, wheel locks, stud conversion kits, and many wheel spacer configurations for installation flexibility.
