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 remove unnecessary material, creating a wheel that delivers an exceptional balance of lightweight performance and durability.
Extensive Finite Element Analysis was utilized throughout development to reinforce high-stress areas while reducing material where it provided no structural advantage. The result is a wheel engineered to handle demanding performance driving conditions without compromising strength.
Engineered for Massive Brake Clearance
High-performance brake systems often require larger and heavier wheel packages, but the EC-7 was specifically engineered to maximize brake clearance while maintaining lightweight 18 inch sizing. Through comprehensive laser scanning and repeated fitment testing, Apex developed the EC-7 to clear many brake systems that typically require larger diameter wheels from competing designs.
Aggressive Concavity and Race-Inspired Styling
The EC-7 utilizes multiple concave face profiles to maximize brake clearance and visual depth across various applications. The aggressive concave profile creates a purposeful motorsport appearance while contributing to reduced wheel weight. Finished in Race Silver, the EC-7 delivers a clean and timeless performance look that complements any Corvette build.
Built for Serious Enthusiasts
Unlike many lightweight wheel designs that require specialized tuner hardware, the EC-7 is engineered to accommodate oversized race lugs and impact sockets. This makes wheel changes quicker and easier during track events, autocross competition, and routine maintenance.
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.
