Premium Lightweight BMW Performance Wheel
The Apex ARC-8 18x8.5 ET45 Flow-Formed Wheel in Hyper Silver delivers lightweight performance, aggressive motorsport styling, and race-proven durability for BMW enthusiasts seeking the perfect balance of street and track capability. Engineered specifically for BMW applications, the ARC-8 improves steering response, handling precision, and overall driving dynamics while maintaining exceptional structural integrity.
Featuring a BMW-specific 5x120 bolt pattern and 72.56mm center bore, this ARC-8 wheel provides true hub-centric fitment for smooth, vibration-free installation. The Hyper Silver finish offers a clean, premium appearance that complements both modern and classic BMW builds while highlighting the ARC-8s iconic split-spoke design.
Advanced Flow-Formed Wheel Technology
Apex utilizes advanced flow-forming manufacturing processes to create a wheel that is both lightweight and exceptionally strong. During production, the wheel barrel is compressed and stretched to improve aluminum grain structure and mechanical properties beyond conventional cast wheel construction.
The result is a wheel with enhanced rigidity, reduced rotational mass, and improved durability without the high cost of full forged construction. Apex also conducts extensive Finite Element Analysis to reinforce critical stress points while eliminating unnecessary material for an optimized strength-to-weight ratio.
Designed for Brake Clearance and Track Use
The ARC-8 was engineered with deep-concave spokes and optimized barrel geometry to provide excellent clearance for many aftermarket BMW big brake kits. Whether your BMW sees spirited street driving, autocross competition, or full track duty, the ARC-8 is built to handle aggressive performance use.
Oversized lug openings accommodate impact sockets and race hardware, allowing for fast and efficient wheel changes during track days and competition events.
