Apex EC-7RS 18x11 Forged Wheel (EC7RS1811ET7-5120-671-AN) - Chevrolet
Built for drivers who refuse to compromise, the Apex EC-7RS takes the iconic EC-7 design and transforms it into an ultra-lightweight forged wheel engineered for serious motorsport performance. As part of Apex's Sprint Line, the EC-7RS delivers reduced rotational mass, exceptional strength, and race-proven durability to help improve acceleration, braking response, and lap times. Finished in Anthracite, this wheel combines aggressive styling with cutting-edge engineering for high-performance Chevrolet applications.
Starting with proprietary motorsport-specific forged blanks, the EC-7RS is designed to withstand the demands of track use while maintaining the lightweight characteristics enthusiasts demand. Advanced side-milled spokes, a reinforced Sprint Spec inner lip, extensive FEA optimization, and independent testing beyond industry standards all contribute to a forged wheel that excels both on the street and at the track.

Forged for Maximum Performance
Each EC-7RS begins as a massive forged aluminum blank weighing up to 120 pounds before machining. Formed under 10,000 metric tons of pressure, the forging process improves grain structure, reduces porosity, and creates an exceptionally strong foundation capable of handling the rigors of competitive driving.
Advanced Side-Milled Spoke Design
One of the defining characteristics of the EC-7RS is its extensive side-milling. Using precision CNC machining, Apex removes material that does not contribute to structural integrity, resulting in lower rotational mass without compromising strength. The result is sharper steering response and improved vehicle dynamics.
Stronger Where It Matters Most
Rather than sacrificing durability to achieve a lower weight target, Apex strategically reinforced critical stress points throughout the wheel. The Sprint Spec inner lip provides increased impact resistance and durability while maintaining an exceptionally lightweight overall package.
Race-Proven Engineering
Extensive Finite Element Analysis was utilized to identify high-stress areas and optimize material placement throughout the wheel. This engineering process allows the EC-7RS to achieve an outstanding balance of strength, stiffness, and low weight.
Independently Tested Beyond Standards
Apex partners with STL, an independent testing laboratory in Ohio, to validate wheel performance. Sprint Line wheels are tested beyond standard JWL requirements through increased load testing, longer test durations, and more severe impact evaluations to ensure long-term durability.
Built for Big Brakes
Leveraging over a decade of brake fitment development and 3D laser scanning technology, Apex engineered the EC-7RS with exceptional brake clearance. The high-clearance barrel and application-specific spoke design allow fitment over many factory and aftermarket performance brake systems.
Track-Ready Features
Paintless knurled bead seats help maximize tire grip under hard acceleration and braking, while oversized lug openings accommodate race hardware and impact sockets for faster wheel changes. Laser-engraved specifications provide easy identification long after installation.
Fitment

FAQs
What makes the EC-7RS different from standard flow-formed wheels?
The EC-7RS utilizes fully forged 6061-T6 aluminum construction, side-milled spokes, proprietary motorsport forgings, and Sprint Line engineering to provide greater strength and lower weight than traditional flow-formed wheels.
Can this wheel be used with factory TPMS sensors?
Yes. The EC-7RS accepts OEM and aftermarket TPMS sensors along with standard valve stems and factory mounting hardware.
