Apex ARC-8RT 17x8.5 Fully Forged Touring Wheel (ARC8RT1785ET40-5120-7256-RS) - BMW
The Apex ARC-8RT blends timeless BMW styling with the advanced engineering and durability serious enthusiasts demand from a modern forged wheel. Finished in Race Silver and purpose-built for BMW applications, this 17x8.5 Touring Line wheel delivers lightweight performance, exceptional rigidity, and motorsport-level strength while preserving the classic ARC-8 design that has become a staple among track drivers and street enthusiasts alike.
