Design & Construction

The RI-A’s design features a refined multi-spoke pattern that balances visual complexity with structural efficiency. Each spoke tapers elegantly toward the rim lip, creating a sense of depth and concavity that enhances the wheel’s aggressive stance without overwhelming the vehicle’s overall aesthetic. The diamond black finish adds a subtle metallic sheen that catches light dynamically, elevating the wheel’s presence whether on the street or at a car meet.

Manufactured using BBS’s renowned forging process, the RI-A benefits from superior strength-to-weight ratio compared to cast wheels. This process involves compressing aluminum billets under extreme pressure to create a dense, uniform grain structure, resulting in a wheel that is both lightweight and exceptionally durable. The finish is applied with precision to ensure long-lasting resistance to corrosion and wear, maintaining the wheel’s appearance and performance over time.
