About the BBS RI-A

The BBS RI-A is engineered using a flow-forming manufacturing process, a technique that applies high pressure rollers to a cast aluminum blank to stretch and compress the barrel, resulting in a wheel that achieves near-forged strength characteristics at a more accessible weight profile. This process refines the grain structure of the aluminum, improving tensile strength and impact resistance compared to conventional gravity casting — a hallmark of BBS wheels engineering precision.

This BBS RI-A is available in 18x9.5, +40mm offset, 5x120 bolt pattern. The Matte Bronze finish features a warm, matte bronze tone with a vintage-inspired character.
