Apex EC-7RS 19x12.5 Forged Wheel 5x120.65 BP / ET55 / 70.3mm CB - Satin Black (Chevrolet) (EC7RS19125ET55-512065-703-NSBK)
The Apex EC-7RS is the ultimate expression of the iconic EC-7 design, engineered for drivers who demand every possible advantage from their wheel package. As part of Apex's Sprint Line of forged wheels, the EC-7RS was developed to reduce rotational mass, improve responsiveness, and deliver the strength required for the most demanding track environments. Finished in Satin Black, this wheel combines aggressive styling with race-proven engineering for Chevrolet enthusiasts who refuse to compromise.
Manufactured from forged 6061-T6 aluminum and built using Apex's proprietary motorsport forging technology, the EC-7RS is designed to maximize performance without sacrificing durability. From advanced side-milled spokes and reinforced Sprint Spec inner lip technology to independent testing and massive brake clearance, every detail serves a purpose both on and off the track.

True Motorsport Blanks
Unlike generic forged wheels that rely on universal blank designs, the EC-7RS starts with proprietary motorsport-specific forgings developed entirely by Apex. This approach allows complete control over wheel geometry, concavity, brake clearance, spoke architecture, and structural reinforcement. The result is a wheel purpose-built for performance driving rather than adapted from a generic design.
10K Tons of Pressure
Each EC-7RS begins as a forged aluminum blank weighing as much as 120 pounds before machining. Using specialized equipment capable of applying 10,000 metric tons of pressure, Apex creates an exceptionally dense aluminum structure with enhanced grain flow and reduced porosity. This process provides the strength necessary to aggressively reduce weight while maintaining durability.
Side-Milled Spokes
The EC-7RS features extensive side-milling that removes unnecessary material from the spokes without compromising strength. Precision CNC machining creates a lighter wheel with reduced rotational inertia, helping improve acceleration, braking response, and steering feedback while preserving the rigidity expected from a premium forged wheel.
A Stronger Lightweight Wheel
Many lightweight wheels achieve their weight savings by sacrificing durability. Apex approached the EC-7RS differently by first removing unnecessary material and then strategically reinforcing critical areas. This process resulted in a wheel that remains exceptionally lightweight while delivering increased inner lip strength and a higher load rating.
Weight Optimized Engineering
Extensive Finite Element Analysis was utilized throughout development to identify stress concentrations and optimize material placement. Every contour of the EC-7RS was carefully engineered to maximize strength while eliminating excess mass, producing a wheel that performs at the highest levels without unnecessary weight.
Independently Tested
Rather than relying solely on simulations and internal validation, Apex subjected the EC-7RS to independent testing through STL in Ohio. Testing standards exceeded JWL requirements through increased load levels, longer testing duration, and more demanding impact procedures, providing additional confidence for enthusiasts who push their vehicles hard.
Tougher Sprint Spec Inner Lip
The Sprint Spec inner lip incorporates a unique channel profile engineered to improve impact resistance and durability. Despite weighing significantly less than many comparable wheels, the EC-7RS features a reinforced inner lip structure that helps withstand the demands of aggressive driving environments.
Massive Brake Clearance
Brake clearance remains a core priority for Apex. Through extensive 3D laser scanning and vehicle-specific engineering, the EC-7RS incorporates a high-clearance barrel design and optimized spoke profiles that accommodate many large factory and aftermarket brake systems.
Deeper Concavity
The advanced forging architecture of the EC-7RS enables deeper concave spoke profiles than previous wheel generations. Each profile is engineered around the specific application to maximize both appearance and performance while maintaining proper brake clearance.
Paintless Knurled Bead Seats
Repeated hard acceleration and braking can cause tire movement along the bead seat. Apex addresses this with paintless knurled bead seats that remain fully effective because the knurling is left exposed rather than painted over. This helps improve tire retention and maintain balance during demanding driving conditions.
Built for Impact Sockets
Track days require fast and efficient wheel changes. The EC-7RS is engineered to accommodate oversized race lugs and impact sockets, eliminating the need for fragile tuner-style hardware and making wheel swaps easier at the track.
Laser-Engraved Specifications
Wheel specifications are laser engraved directly onto the barrel, making them easy to locate and read throughout the life of the wheel. This attention to detail simplifies maintenance, tire changes, and trackside inspections.
Hub Centric Design
The EC-7RS is engineered as a hub-centric wheel for its intended applications, minimizing the need for centering rings while promoting proper fitment and load distribution.
Center Caps, Hardware & TPMS Compatibility
Every EC-7RS includes an Apex gloss black center cap and works with OEM mounting hardware, quality aftermarket hardware, wheel spacers, wheel locks, and stud conversion kits. The wheel is also compatible with OEM and aftermarket TPMS sensors and standard valve stems.
