Premium Lightweight Wheels for BMW Enthusiasts
The Apex ARC-8 18x8.5 ET38 Flow-Formed Wheel in Hyper Silver delivers lightweight motorsport performance, aggressive concave styling, and race-proven durability for BMW enthusiasts who demand both style and function. Engineered specifically for high-performance street driving and track use, the ARC-8 improves handling response, steering precision, and overall chassis dynamics while maintaining exceptional strength.
Featuring a BMW-specific 5x120 bolt pattern and 72.56mm center bore, this wheel offers true hub-centric fitment for a precise installation without requiring centering rings in most applications. The Hyper Silver finish provides a clean, premium appearance that highlights the ARC-8s classic motorsport-inspired spoke design.
Advanced Flow-Formed Construction
Apex utilizes advanced flow-forming technology to strengthen the wheel barrel while reducing unnecessary weight. During the manufacturing process, the aluminum barrel is compressed and stretched to improve grain structure, increasing barrel rigidity and durability beyond what conventional cast wheels can provide.
This construction process allows the ARC-8 to deliver many of the advantages associated with forged wheels while remaining far more affordable. Extensive Finite Element Analysis was also used throughout development to reinforce critical stress areas while removing excess material wherever possible for optimal weight savings.
Optimized Brake Clearance and Concavity
The ARC-8s deep-concave spoke profile was carefully engineered to maximize brake clearance while maintaining aggressive styling. The wheel accommodates many popular aftermarket big brake kits, making it an excellent option for serious performance-oriented BMW builds.
Oversized lug openings also allow the use of race lugs and impact sockets, simplifying wheel changes during track events and competition use.
