• Sold as a single wheel; purchase quantity based on your build
• TPMS compatible; valve stem included

Features

• One-piece die-forged aluminum construction - engineered to the same specification as BBS's SUPER GT race wheels
• BBS-patented milling process applied inside the spoke area for maximum weight reduction without structural compromise
• Five V-spoke design optimized via FEM (Finite Element Method) analysis for ideal stiffness-to-weight ratio
• Anti-slip paint on the tire bead seat minimizes movement between wheel and tire under high lateral loads
• Steel bushings in lug holes protect the wheel during installation and removal - a motorsport-derived detail
• Diamond Silver finish with clear protective topcoat - refined, race-proven aesthetic

Product Description

The BBS RIA058DS is the rear-axle wheel in the factory-recommended staggered setup for the Porsche 997 Narrowbody platform, sized at a wide 19x12 with a +61mm offset to fill the rear arches of the 997 Carrera, Carrera S, and GT3. Built in Japan by BBS using the same engineering principles as their SUPER GT racing wheels, the RI-A features one-piece die-forged aluminum construction, BBS's patented spoke-area milling process, and FEM-optimized geometry - all contributing to a wheel that is both exceptionally light and structurally rigid.

Purpose-built for the 5x130 Porsche bolt pattern with a 71.6mm centerbore, this wheel bolts directly to the 997 NB hub with no modifications or adapters required. The 19x12 rear width paired with the 19x9 front (RIA056DS) creates the correct staggered fitment BBS and the 997 NB platform were designed for. Anti-slip bead paint and steel lug hole bushings are included as motorsport-derived functional details, making this a track-capable wheel equally suited to spirited street driving on one of Porsche's most celebrated chassis generations.
