Apex ARC-8 18x8.5 Flow-Formed Wheel 5x120 BP / ET45 / 72.56mm CB - Satin Black (BMW) ARC81885ET45-5120-7256-SMBK
Track-Proven Lightweight Performance for BMW Applications
The Apex ARC-8 18x8.5 ET45 Flow-Formed Wheel in Satin Black delivers the perfect combination of lightweight performance, aggressive styling, and race-ready durability for BMW enthusiasts. Designed specifically for BMW applications, the ARC-8 improves steering response, handling precision, and overall chassis balance while maintaining the strength needed for both street and track use.
Featuring a BMW-specific 5x120 bolt pattern and 72.56mm center bore, this wheel offers true hub-centric fitment without requiring centering rings. The Satin Black finish complements the ARC-8s iconic deep-concave spoke design, creating a clean motorsport-inspired appearance that looks equally at home on daily drivers and dedicated track builds.
Advanced Flow-Formed Construction
Apex utilizes advanced flow-forming technology to create a wheel that combines reduced weight with exceptional structural rigidity. During production, the barrel is stretched and compressed to improve aluminum grain structure and strengthen the wheel beyond what traditional cast construction can achieve.
Extensive Finite Element Analysis was used to reinforce high-stress areas while removing unnecessary material, resulting in a lightweight wheel that maintains outstanding durability and impact resistance under demanding driving conditions.
Designed for Big Brake Clearance and Motorsport Use
The ARC-8 was engineered with performance driving in mind. Its optimized barrel profile and deep-concave spoke layout provide excellent clearance for many aftermarket BMW big brake kits while preserving ideal spoke strength and fitment geometry.
Oversized lug openings allow the use of impact sockets and race lug hardware, making wheel swaps faster and easier during track days or competition events.
