This \u003cstrong\u003eRIA058DS\u003c\/strong\u003e measures 19x12 with a 5x130 bolt pattern, ET+61 offset, and a 71.6mm center bore, making it a precision fitment solution for the Porsche 997 platform. Finished in Diamond Silver with a clear coat, and manufactured in Japan by BBS Japan Co., Ltd., the \u003cstrong\u003eRIA058DS\u003c\/strong\u003e represents BBS's commitment to combining motorsport engineering with OEM-level fitment precision.\u003c\/p\u003e\n\n\u003ch4\u003eConstruction and Engineering\u003c\/h4\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eBBS RIA058DS\u003c\/strong\u003e is constructed as a 1-piece forged monoblock, the process most associated with maximum structural uniformity and minimal material variation. Forging compresses and aligns the grain structure of the aluminum alloy, producing a wheel that is both strong and light. The \u003cstrong\u003eRIA058DS\u003c\/strong\u003e weighs 10.1 kg (22.2 lbs), a notable achievement for a 19x12 rear wheel intended for a high-performance rear-engine sports car platform.\u003c\/p\u003e\n\n\u003cp\u003eThe 5-spoke design of the \u003cstrong\u003eRIA058DS\u003c\/strong\u003e is clean and purposeful, reflecting BBS's motorsport design language while accommodating the large brake calipers and rotors found on Porsche 997 variants. The wheel features an anti-slip knurled bead seat, which provides an additional mechanical interface between the tire bead and the wheel rim under the high lateral loads generated during performance driving. Steel bushings are incorporated at the lug hole positions to distribute clamping forces evenly and protect the aluminum at the fastening points.\u003c\/p\u003e\n\n\u003cp\u003eThis is a made-to-order product.

BBS has been involved in motorsport at the highest levels, supplying wheels to Formula 1 teams, Le Mans prototype programs, and factory GT racing operations. The RI-A series is BBS's forged monoblock line designed for fitment-specific, platform-dedicated applications where dimensional precision and weight minimization are equally critical. Each \u003cstrong\u003eRIA058DS\u003c\/strong\u003e wheel is produced to tight tolerances that reflect the engineering culture driving the BBS brand.\u003c\/p\u003e\n\n\u003ch4\u003eCalifornia Proposition 65 Warning\u003c\/h4\u003e\n\n\u003cp\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e This product can expose you to chemicals including lead and lead compounds, which are known to the State of California to cause cancer and birth defects or other reproductive harm.

To fit all four corners of a Porsche 997, add 4 units to your cart. Note that front and rear wheel sizing on the 997 may differ; verify the correct part numbers for each axle position before ordering.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is PFS and why is it required for the RIA058DS?\u003c\/strong\u003e\u003cbr\u003e\nPFS stands for Press Fit System, BBS's hub-centric ring system. The 71.6mm center bore of the \u003cstrong\u003eRIA058DS\u003c\/strong\u003e requires either an 82mm PFS hub ring or a spring clip to bridge the gap between the wheel bore and your vehicle's hub flange diameter. Without this hardware, the wheel will not seat concentrically on the hub, which can lead to vibration and uneven stress on the wheel studs. The PFS ring or spring clip is sold separately and must be obtained before installation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs the RIA058DS compatible with my Porsche 997?\u003c\/strong\u003e\u003cbr\u003e\nThe \u003cstrong\u003eRIA058DS\u003c\/strong\u003e is designed for Porsche 997 Carrera, Carrera S, Carrera 4, Carrera 4S, GT3, GT3 RS, Turbo, and Turbo S. It is not compatible with Bentley, BMW iX\/X7\/M5, Maybach, Mercedes-Benz EQC\/GLS, Rolls Royce, Lamborghini Urus, Audi RS3\/TT RS, or heavy SUVs and battery-electric vehicles. Confirm your specific build date and trim before ordering.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAre tires included with the RIA058DS?\u003c\/strong\u003e\u003cbr\u003e\nNo. Tires are not included. The \u003cstrong\u003eRIA058DS\u003c\/strong\u003e is sold as a bare wheel. Tires must be purchased and mounted separately by a qualified installer.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAre lug nuts included with the RIA058DS?\u003c\/strong\u003e\u003cbr\u003e\nLug nuts are not included. Porsche 997 applications typically use ball-seat or shank-style lug bolts rather than nuts. Consult your vehicle documentation or a qualified Porsche specialist to source the correct fasteners for your application.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the center bore of the RIA058DS?\u003c\/strong\u003e\u003cbr\u003e\nThe center bore is 71.6mm. An 82mm PFS hub ring or spring clip (sold separately) is required to properly seat this wheel on the hub of compatible Porsche 997 vehicles.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat does made to order mean for the RIA058DS?\u003c\/strong\u003e\u003cbr\u003e\nMade to order means the \u003cstrong\u003eRIA058DS\u003c\/strong\u003e is not carried as a stocked item. Each wheel is produced upon confirmed order placement with BBS Japan. Lead times vary. Contact us prior to ordering if you have a deadline, and we will provide the most current production and shipping estimate available.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat warranty does the RIA058DS carry?\u003c\/strong\u003e\u003cbr\u003e\nThe \u003cstrong\u003eRIA058DS\u003c\/strong\u003e carries a BBS limited manufacturer warranty covering defects in materials and workmanship under normal use conditions. The warranty does not cover damage from road hazards, improper installation, chemical exposure, curb impact, or modifications. Contact your authorized BBS retailer to initiate any warranty claim.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the knurled bead seat on the RIA058DS?\u003c\/strong\u003e\u003cbr\u003e\nThe anti-slip knurled bead seat is a textured surface machined into the wheel's rim bead area. This texture creates additional friction between the tire bead and the wheel rim, helping to resist tire rotation on the rim under the high cornering loads generated during performance driving. It is a feature commonly found on motorsport and high-performance street wheels.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat are the steel bushings in the RIA058DS?\u003c\/strong\u003e\u003cbr\u003e\nSteel bushings are pressed into the lug hole positions of the wheel. Because aluminum is softer than steel, direct contact between lug bolts and aluminum can cause galling or deformation over time, particularly under the high torque and thermal cycling of performance driving. Steel bushings protect the lug holes and ensure consistent, reliable clamping force throughout the service life of the \u003cstrong\u003eRIA058DS\u003c\/strong\u003e.\u003c\/p\u003e","brand":"BBS","offers":[{"title":"Default Title","offer_id":45948891299919,"sku":"BBSRIA058DS","price":1620.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1062\/7920\/files\/bbs-ria058ds-19x12-5x130-et61-cb71_6-diamond-silver-forged-wheel-82mm-pfs-required-bbs_9a320884.png?v=1782275243","url":"https:\/\/www.blackopsautoworks.com\/products\/bbs-ria058ds-19x12-5x130-et61-cb71-6-diamond-silver-forged-wheel-82mm-pfs-required","provider":"Black Ops Auto Works","version":"1.0","type":"link"}
