BBS - BBS-RIA018DB

This BBS RI-A series wheel, with MPN RIA018DB, features a Diamond Black finish and measures 18 inches in diameter with a 9.5-inch width. It has an offset of +35mm and a bolt pattern of 5x114.3mm (5x4.5). The hub bore is 82mm, backspacing is 6.63 inches, and frontspacing is 3.87 inches. Constructed from forged aluminum, it utilizes a BBS patented milling process inside the spoke area and is weight-optimized by FEM analysis. The design is based on the same concept as BBS' wheels for SUPER GT racing in Japan. Features include anti-slip paint to minimize slipping between the wheel and tire, and steel bushings to protect the nut holes during installation and removal. BBS has been employing flow-forming since 1996, a process that uses continuous rotational motion with hydraulic rollers and high pressure at high temperatures to form the inner rim area, enhancing strength, stiffness, and impact resistance.
