Apex ARC-8RT 17x8.5 Fully Forged Touring Wheel (ARC8RT1785ET40-5120-7256-BC) - BMW
The Apex ARC-8RT takes the legendary ARC-8 design BMW enthusiasts have trusted for years and elevates it with fully forged construction, advanced engineering, and motorsport-grade durability. Finished in Brushed Clear and purpose-built for BMW applications, this 17x8.5 wheel combines lightweight performance, exceptional brake clearance, and increased structural rigidity while preserving the timeless split-spoke styling that made the ARC-8 iconic in the first place.
Manufactured from fully forged 6061-T6 aluminum using an extreme 10,000 ton forging process, the ARC-8RT achieves superior strength, reduced porosity, and improved grain structure over conventional wheel manufacturing methods. Apex engineers redesigned the spoke geometry with thinner yet deeper spokes to improve stiffness without increasing weight. Combined with the reinforced Sprint Spec inner lip and optimized barrel design, the ARC-8RT is engineered to handle aggressive street driving, track sessions, and harsh road conditions with confidence.
