Apex EC-7RS 18x12.5 Forged Wheel (EC7RS18125ET52-512065-703-NSBK) - Chevrolet
The Apex EC-7RS represents the most advanced evolution of the legendary EC-7 wheel design. Developed as part of Apex's Sprint Line of forged wheels, the EC-7RS combines reduced weight, increased strength, and race-proven durability to help drivers extract maximum performance on the street, track, or autocross course. Finished in Satin Black, this fully forged wheel delivers aggressive styling backed by uncompromising engineering.
Built using proprietary motorsport-specific forged blanks, the EC-7RS incorporates extensive side milling, advanced FEA optimization, a reinforced Sprint Spec inner lip, and independent third-party testing beyond industry standards. Every detail was designed to create an exceptionally lightweight wheel without sacrificing durability, brake clearance, or long-term reliability.

Sprint Line Forged Performance
The EC-7RS starts life as a massive forged aluminum blank weighing up to 120 pounds before machining. Produced under 10,000 metric tons of pressure, the forging process significantly improves aluminum grain structure and density while reducing porosity. The result is an incredibly strong foundation capable of handling the demands of competitive motorsports and high-performance driving.
Side-Milled Weight Reduction
A key upgrade found on the EC-7RS is its aggressive side-milled spoke design. Precision CNC machining removes unnecessary material from the spoke structure while maintaining critical strength. This process helps reduce rotational mass, improve responsiveness, and deliver faster acceleration and braking performance.
Stronger Where It Matters
Instead of pursuing lightweight numbers at the expense of durability, Apex strategically reinforced critical load-bearing areas. The Sprint Spec inner lip features a unique channel profile that improves impact resistance and strength, helping the EC-7RS withstand the punishment of track use while remaining exceptionally lightweight.
Verified Through Independent Testing
Every Sprint Line wheel undergoes extensive third-party validation through STL, an independent testing laboratory. Testing exceeds traditional JWL requirements through increased loads, greater impact severity, and longer testing durations, providing confidence for both street and competition use.
Engineered for Big Brake Packages
Utilizing over a decade of brake fitment development and advanced 3D laser scanning technology, Apex engineered the EC-7RS with a high-clearance barrel design and optimized spoke geometry. This allows the wheel to accommodate many factory and aftermarket high-performance brake systems without compromising strength or appearance.
Track-Ready Details
Paintless knurled bead seats help prevent tire slippage under heavy acceleration and braking, while oversized lug openings accommodate race hardware and impact sockets for rapid wheel changes. Laser-engraved specifications ensure critical wheel information remains easy to locate and read throughout the life of the wheel.
Fitment
- Chevrolet Applications Utilizing 5x120.65 Bolt Pattern and 70.3mm Center Bore
