Sprint Line Forged Performance
The EC-7RS was developed for drivers who refuse to compromise between strength and weight. Built using Apex's advanced forging process, each wheel begins as a massive forged aluminum blank before extensive CNC machining transforms it into a lightweight, high-strength performance wheel engineered to withstand demanding track conditions.
10,000 Tons of Forging Force
Each forged blank is created using specialized equipment capable of producing 10,000 metric tons of pressure. This intense forging process improves grain structure, eliminates porosity, and creates a stronger aluminum foundation that allows Apex engineers to remove unnecessary weight while maintaining exceptional durability.
Purpose-Built Motorsport Forgings
Unlike manufacturers using generic third-party forgings, Apex develops proprietary blank profiles specifically for motorsport applications. This allows complete control over spoke design, barrel shape, brake clearance, concavity, and structural integrity.
Advanced Side-Milled Spoke Design
The EC-7RS features aggressive side-milled spokes that remove excess material through precision CNC machining. This advanced process reduces rotational mass while maintaining the strength and stiffness required for high-performance driving and competitive motorsports.
Engineered Strength Without Excess Weight
Apex carefully optimized the EC-7RS by removing unnecessary material throughout the wheel while strategically reinforcing critical load-bearing areas. The result is an exceptionally lightweight wheel that retains the durability needed for repeated track use and aggressive driving.
FEA Optimized Construction
Extensive Finite Element Analysis was utilized during development to identify stress concentrations and optimize material placement. This engineering approach allows the EC-7RS to achieve impressive weight savings while maintaining the structural integrity expected from a true motorsport wheel.
Independently Tested for Confidence
Rather than relying solely on computer simulations, Apex validates its Sprint Line wheels through independent third-party testing. Testing exceeds standard JWL requirements with increased loads, longer test durations, and more demanding impact evaluations.
Sprint Spec Reinforced Inner Lip
The Sprint Spec inner lip incorporates a unique reinforced channel profile designed to increase impact resistance. This advanced design delivers greater durability than previous generations while maintaining the lightweight characteristics that define the EC-7RS platform.
Massive Brake Clearance
Using extensive 3D laser scanning and application-specific engineering, Apex designed the EC-7RS with a high-clearance barrel profile and optimized spoke geometry to accommodate many large factory and aftermarket brake systems.
Deep Concavity and Aggressive Styling
The advanced forged architecture allows for deeper concave spoke profiles than traditional wheel designs. Each profile is engineered to balance aesthetics, brake clearance, and structural performance for its intended application.
Paintless Knurled Bead Technology
To reduce tire slippage during hard acceleration and braking, the EC-7RS utilizes paintless knurled bead seats. Unlike painted knurling that can lose effectiveness over time, the exposed knurled surface helps maintain maximum grip between the tire and wheel.
Track-Ready Details
The EC-7RS is designed for enthusiasts who regularly service and swap wheels. Oversized race lug compatibility allows the use of impact sockets, while laser-engraved specifications provide easy identification at the track or in the garage.
OEM Compatibility
This wheel is compatible with OEM and aftermarket TPMS sensors, factory and aftermarket mounting hardware, wheel locks, stud conversion kits, and most wheel spacer setups. A gloss black Apex center cap is included with every wheel.
