Track-Proven Lightweight BMW Wheel Performance
The Apex ARC-8 18x8.5 ET38 Flow-Formed Wheel in Satin Black combines lightweight construction, aggressive styling, and race-ready durability for BMW enthusiasts who demand exceptional performance both on the street and at the track. Designed specifically for BMW applications, the ARC-8 improves steering response, handling precision, and overall driving feel while maintaining the durability required for demanding performance use.
Featuring a BMW-specific 5x120 bolt pattern and 72.56mm center bore, this ARC-8 wheel delivers true hub-centric fitment for precise installation and vibration-free performance. The Satin Black finish adds a clean, aggressive appearance that pairs perfectly with both modern and classic BMW platforms.
Advanced Flow-Formed Wheel Construction
Apex uses advanced flow-forming manufacturing technology to improve barrel strength while significantly reducing wheel weight. During production, the barrel is compressed and stretched to enhance aluminum grain structure and mechanical properties beyond conventional cast wheels.
This process produces a lightweight wheel with exceptional rigidity, improved impact resistance, and track-capable durability without the premium cost associated with forged wheels. Apex also performs extensive Finite Element Analysis to strengthen high-stress areas while removing unnecessary material for an optimized strength-to-weight ratio.
Built for Brake Clearance and Motorsport Use
The ARC-8 was engineered with deep-concave spokes and optimized barrel geometry to provide outstanding brake clearance for many popular BMW big brake kits. Whether your BMW sees daily driving, autocross competition, or dedicated track use, the ARC-8 is built to perform under pressure.
Oversized lug openings allow the use of race lugs and impact sockets, making wheel changes faster and easier during track days and competition events.
