Apex ARC-8 18x8.5 Flow-Formed Wheel 5x120 BP / ET38 / 72.56mm CB - Anthracite (BMW) ARC81885ET38-5120-7256-AN
Lightweight BMW Wheels Built for Performance
The Apex ARC-8 18x8.5 ET38 Flow-Formed Wheel in Anthracite delivers race-inspired styling, lightweight construction, and track-ready durability for BMW enthusiasts seeking serious performance upgrades. Designed specifically for demanding street and motorsport applications, the ARC-8 combines aggressive concavity, optimized brake clearance, and reduced rotational weight to improve handling, steering feel, and overall driving response.
Built around a BMW-specific 5x120 bolt pattern and 72.56mm center bore, this ARC-8 wheel provides true hub-centric fitment for a precise installation without the need for centering rings in most applications. The Anthracite finish adds a clean, aggressive appearance that pairs perfectly with both modern and classic BMW builds.
Advanced Flow-Formed Construction
Apex utilizes advanced flow-forming technology to create a wheel that delivers increased barrel strength and rigidity while minimizing unnecessary weight. During production, the barrel is compressed and stretched to improve the aluminum grain structure, producing a wheel that offers many of the advantages of forged construction without the higher price tag.
To further optimize performance, Apex uses extensive Finite Element Analysis to reinforce high-stress areas while removing material where it does not contribute to structural integrity. The result is an exceptionally lightweight and durable wheel engineered for aggressive driving conditions both on the street and at the track.
Big Brake Clearance and Deep Concavity
The ARC-8 was engineered to accommodate many aftermarket big brake kits while maintaining its signature deep-concave spoke profile. Apex carefully designed multiple face profiles to maximize concavity without sacrificing brake clearance or structural integrity.
Oversized lug openings allow the use of impact sockets and race hardware, making wheel changes quick and efficient during track events and competition use.
