Advanced Flow-Formed Construction
Apex uses advanced flow-forming technology to increase barrel strength while minimizing overall wheel weight. During the manufacturing process, the barrel is compressed and stretched to improve aluminum grain structure and mechanical properties beyond traditional cast wheels.
The result is a wheel with enhanced rigidity, reduced rotational mass, and increased durability without the premium cost typically associated with forged wheels. Apex also applies extensive Finite Element Analysis to optimize material placement throughout the wheel, reinforcing critical stress areas while eliminating unnecessary weight.
Track-Ready Brake Clearance and Fitment
The ARC-8 was engineered with deep-concave spokes and optimized barrel geometry to provide excellent big brake clearance for many popular BMW performance brake upgrades. Whether your car sees canyon roads, autocross events, or full track sessions, the ARC-8 is designed to handle aggressive driving demands.
Oversized lug openings accommodate race lugs and impact sockets, making wheel changes fast and convenient during track days and competition use.
