Apex ARC-8 18x8.5 Flow-Formed Wheel 5x120 BP / ET45 / 72.56mm CB - Anthracite (BMW) ARC81885ET45-5120-7256-AN
Lightweight BMW Wheel Performance with Motorsport Styling
The Apex ARC-8 18x8.5 ET45 Flow-Formed Wheel in Anthracite delivers race-inspired performance, lightweight construction, and aggressive styling for BMW enthusiasts looking to improve handling and overall driving dynamics. Engineered specifically for BMW applications, the ARC-8 combines reduced rotational mass with exceptional durability for both street and track use.
Featuring a BMW-specific 5x120 bolt pattern and 72.56mm center bore, this ARC-8 wheel provides true hub-centric fitment for proper balance and vibration-free installation. The Anthracite finish adds a premium motorsport appearance that pairs perfectly with modern and classic BMW builds alike.
Advanced Flow-Formed Construction Technology
Apex utilizes advanced flow-forming manufacturing techniques to strengthen the wheel barrel while minimizing overall weight. During production, the barrel is compressed and stretched to improve aluminum grain structure and mechanical properties beyond what conventional cast wheels can offer.
This process creates a wheel with improved rigidity, enhanced impact resistance, and reduced weight without the cost of full forged construction. Apex also uses extensive Finite Element Analysis to reinforce critical stress points while eliminating unnecessary material for an optimized strength-to-weight ratio.
Track-Ready Engineering and Brake Clearance
The ARC-8 was designed with performance driving in mind. Deep-concave spokes 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 allow the use of race lugs and impact sockets, making wheel changes faster and easier during track days and motorsport events.
