Race-Inspired BMW Wheel Performance
The Apex ARC-8 18x8.5 ET45 Flow-Formed Wheel in Hyper Black combines lightweight construction, aggressive styling, and motorsport durability for BMW enthusiasts looking to maximize both performance and appearance. Purpose-built for BMW applications, the ARC-8 improves steering response, handling precision, and overall vehicle dynamics while maintaining exceptional structural strength for demanding driving conditions.
Featuring a BMW-specific 5x120 bolt pattern and 72.56mm center bore, this ARC-8 wheel delivers true hub-centric fitment for smooth, vibration-free installation. The Hyper Black finish gives the wheel a premium, high-contrast appearance that enhances the ARC-8s iconic deep-concave spoke design.
Advanced Flow-Formed Construction
Apex utilizes advanced flow-forming manufacturing technology to improve wheel strength while reducing overall weight. During production, the wheel barrel is compressed and stretched to refine aluminum grain structure and improve mechanical properties beyond traditional cast wheel construction.
This process results in a wheel with exceptional rigidity, improved impact resistance, and reduced rotational mass without the high price typically associated with forged wheels. Apex also performs extensive Finite Element Analysis to strengthen high-stress areas while eliminating unnecessary material for optimal performance.
Built for Brake Clearance and Track Use
The ARC-8 was engineered with aggressive brake clearance and motorsport use in mind. Its deep-concave spoke design and optimized barrel geometry provide excellent clearance for many aftermarket BMW big brake kits while maintaining a lightweight and aggressive wheel profile.
Oversized lug openings accommodate race lugs and impact sockets, allowing for quick and easy wheel swaps during track days and competition events.
