The BBS FI-R Diamond Black wheel showcases BBS's motorsport heritage through one-piece forged monoblock construction that delivers exceptional strength while reducing unsprung weight. This Diamond Black finish provides a sophisticated, stealthy appearance that complements high-performance sports cars and luxury sedans. BBS utilizes advanced forging techniques and finite element analysis to optimize spoke geometry, creating a wheel that's both structurally sound and visually striking. The FI-R features back-milled spokes that strategically remove material where it's not needed for structural integrity, further reducing rotational mass without compromising durability. Available in various sizing configurations with multiple bolt patterns, this wheel accommodates a range of performance vehicles from brands like BMW, Audi, Porsche, and Chevrolet. The Diamond Black finish resists corrosion and maintains its appearance through daily driving and spirited track sessions. Each wheel includes center caps and is backed by BBS's manufacturer warranty. The FI-R's design balances aggressive aesthetics with functional performance benefits, making it suitable for enthusiasts who demand both form and function from their wheel choice.
