Apex EC-7RS 19x12.5 Forged Wheel 5x120.65 BP / ET55 / 70.3mm CB - Anthracite (Chevrolet) (EC7RS19125ET55-512065-703-AN)
The Apex EC-7RS takes the proven motorsport heritage of the iconic EC-7 design and pushes it to the next level with Sprint Line forged technology. Designed for enthusiasts who demand every possible advantage on the street, track, or autocross course, the EC-7RS delivers exceptional weight savings, increased strength, and uncompromising durability. Finished in Anthracite, this wheel combines race-ready engineering with a refined appearance that perfectly complements modern Chevrolet performance platforms.
Built from forged 6061-T6 aluminum and engineered using proprietary motorsport-specific forgings, the EC-7RS was developed to withstand the demands of serious driving while maximizing responsiveness. From advanced side-milled spokes and a reinforced Sprint Spec inner lip to industry-leading brake clearance and independent testing beyond JWL standards, every aspect of this wheel was engineered with performance in mind.

True Motorsport Blanks
Many forged wheels begin with generic blanks that limit wheel design, brake clearance, and concavity. Apex developed proprietary motorsport forging blanks specifically for performance applications, allowing complete control over spoke geometry, barrel design, structural reinforcement, and fitment optimization. This approach delivers a wheel purpose-built for enthusiasts who demand more than an ordinary forged wheel.
10K Tons of Pressure
Each EC-7RS starts as a forged aluminum blank weighing as much as 120 pounds before machining. Formed under 10,000 metric tons of pressure, the forging process enhances grain structure, minimizes porosity, and creates an exceptionally strong foundation that allows Apex engineers to reduce weight without compromising durability.
Side-Milled Spokes
A defining feature of the EC-7RS is its extensively side-milled spoke design. Precision CNC machining removes unnecessary material from low-stress areas, reducing rotational mass while preserving the stiffness and strength required for demanding performance environments. The result is quicker response, improved acceleration characteristics, and sharper handling feel.
A Stronger Lightweight Wheel
Rather than simply chasing the lowest possible weight, Apex focused on creating a stronger lightweight wheel. After optimizing the design for weight reduction, engineers strategically reinforced critical load-bearing areas and the inner lip structure to improve durability and increase load capacity. The result is a wheel capable of handling aggressive driving without the compromises often associated with ultra-lightweight designs.
Weight Optimized Engineering
Extensive Finite Element Analysis was used throughout development to identify high-stress zones and remove material only where it did not contribute to strength. This engineering-driven process allows the EC-7RS to achieve exceptional weight savings while maintaining the structural integrity expected from a premium forged wheel.
Independently Tested
Apex believes wheel performance should be validated through independent testing, not just computer simulations. The EC-7RS was tested by STL, an independent testing laboratory in Ohio, using standards that exceed JWL requirements. Increased testing duration, greater impact forces, and higher load levels help ensure confidence both on and off the track.
Tougher Sprint Spec Inner Lip
The Sprint Spec inner lip utilizes a unique channel profile engineered to improve impact resistance and durability. Even though the EC-7RS is significantly lighter than many comparable wheels, its reinforced inner barrel structure delivers greater strength where it matters most.
Massive Brake Clearance
Brake clearance has been a core focus of Apex wheel development for more than a decade. Using advanced 3D laser scanning and application-specific engineering, the EC-7RS incorporates a high-clearance barrel design and optimized spoke geometry that accommodate many large factory and aftermarket brake systems.
Deeper Concavity
The advanced forging architecture of the EC-7RS allows Apex to create deeper and more aggressive concave spoke profiles than previous generations. Each profile is engineered around the specific application to maximize both aesthetics and performance without compromising clearance requirements.
Paintless Knurled Bead Seats
Hard acceleration and braking can cause tire movement on the wheel barrel, potentially leading to balance issues. Apex combats this with paintless knurled bead seats that maintain maximum effectiveness by leaving the knurling exposed rather than coating it with paint. The result is improved tire retention during demanding driving conditions.
Built for Impact Sockets
Track enthusiasts need wheels that work with track tools. The EC-7RS is designed to accommodate oversized race lugs and impact sockets, making wheel changes faster and easier without requiring specialized tuner-style hardware.
Laser-Engraved Specifications
Wheel specifications are laser engraved directly onto the barrel for easy identification. Unlike traditional stamped markings that can become difficult to read over time, laser engraving provides a clean and durable solution that remains visible throughout the life of the wheel.
Hub Centric Design
The EC-7RS is engineered as a hub-centric wheel for its intended applications, minimizing the need for centering rings and helping ensure proper fitment and load distribution.
Center Caps, Hardware & TPMS Compatibility
Every EC-7RS includes an Apex gloss black center cap and is compatible with OEM mounting hardware, quality aftermarket hardware, wheel spacers, wheel locks, and stud conversion kits. OEM and aftermarket TPMS sensors are fully supported, along with standard valve stems.
