Apex ARC-8 18x8.5 Flow-Formed Wheel 5x120 BP / ET45 / 72.56mm CB - Racing Silver (BMW) ARC81885ET45-5120-7256-RS
Lightweight BMW Performance Wheel Engineering
The Apex ARC-8 18x8.5 ET45 Flow-Formed Wheel in Racing Silver delivers race-inspired performance, aggressive styling, and proven durability for BMW enthusiasts who demand more from their wheel setup. Engineered specifically for BMW applications, the ARC-8 improves handling response, reduces rotational mass, and provides 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 for precise installation and vibration-free performance. The Racing Silver finish highlights the ARC-8s signature deep-concave spoke design while delivering a clean motorsport appearance that complements a wide variety of BMW builds.
Flow-Formed Construction Advantage
Apex utilizes advanced flow-forming technology to produce a wheel that combines lightweight characteristics with exceptional structural rigidity. During manufacturing, the barrel is stretched and compressed to improve aluminum grain structure and increase overall strength compared to conventional cast wheels.
The result is a wheel that provides forged-like performance characteristics at a more accessible price point. Apex also incorporates extensive Finite Element Analysis to strengthen critical stress zones while removing unnecessary material for optimal weight savings and durability.
Optimized for Brake Clearance and Track Duty
The ARC-8 was designed with motorsport performance in mind. Its deep-concave spoke profile and optimized barrel geometry provide excellent clearance for many aftermarket BMW big brake kits without sacrificing wheel strength or fitment quality.
Oversized lug openings support impact sockets and race lug hardware, making wheel changes faster and easier during track events or performance driving sessions.
