Apex ARC-8 18x8.5 Flow-Formed Wheel 5x120 BP / ET38 / 72.56mm CB - Hyper Black (BMW) ARC81885ET38-5120-7256-NHBK
Motorsport-Inspired BMW Wheel Performance
The Apex ARC-8 18x8.5 ET38 Flow-Formed Wheel in Hyper Black combines lightweight motorsport engineering, aggressive concave styling, and race-proven durability for BMW enthusiasts who demand maximum performance both on the street and at the track. Engineered specifically for BMW applications, the ARC-8 improves handling response, steering precision, and chassis balance while delivering a bold, aggressive appearance.
Designed with a BMW-specific 5x120 bolt pattern and 72.56mm center bore, this wheel offers true hub-centric fitment for precise installation and smooth operation without requiring centering rings in most applications. The Hyper Black finish delivers a deep metallic appearance that enhances the ARC-8s signature motorsport-inspired spoke design.
Advanced Flow-Formed Construction
Apex utilizes advanced flow-forming technology to strengthen the wheel barrel while minimizing overall weight. During production, the aluminum barrel is compressed and stretched to improve grain structure, increasing barrel strength and rigidity beyond conventional cast wheel construction.
This manufacturing method allows the ARC-8 to deliver many of the benefits associated with forged wheels while maintaining a significantly lower price point. Apex also uses extensive Finite Element Analysis during development to reinforce high-stress areas while removing excess material wherever possible for optimal performance and durability.
Optimized for Brake Clearance and Aggressive Fitment
The ARC-8s deep-concave spoke profile was specifically engineered to maximize brake clearance while maintaining aggressive styling. The wheel accommodates many popular aftermarket big brake kits, making it ideal for performance-oriented BMW builds and dedicated track setups.
Oversized lug openings support race lugs and impact sockets, making wheel swaps faster and easier during track days and competition use.
