BBS RIA058DS 19x12 5x130 ET61 CB71.6 Diamond Silver Forged Wheel 82mm PFS Required

BBS RIA058DS 19x12 5x130 ET61 CB71.6 Diamond Silver Wheel

The BBS RIA058DS is a 1-piece forged monoblock wheel from the BBS RI-A series, built specifically for performance Porsche applications. This RIA058DS 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 RIA058DS represents BBS's commitment to combining motorsport engineering with OEM-level fitment precision.

Construction and Engineering

The BBS RIA058DS 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 RIA058DS 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.

The 5-spoke design of the RIA058DS 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.

Frequently Asked Questions

Is the RIA058DS sold as a set or individually?
The RIA058DS is sold individually, one wheel per purchase. 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.

What is PFS and why is it required for the RIA058DS?
PFS stands for Press Fit System, BBS's hub-centric ring system. The 71.6mm center bore of the RIA058DS 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.

Is the RIA058DS compatible with my Porsche 997?
The RIA058DS 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.

Are tires included with the RIA058DS?
No. Tires are not included. The RIA058DS is sold as a bare wheel. Tires must be purchased and mounted separately by a qualified installer.

Are lug nuts included with the RIA058DS?
Lug 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.

What is the center bore of the RIA058DS?
The 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.

What does made to order mean for the RIA058DS?
Made to order means the RIA058DS 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.

What warranty does the RIA058DS carry?
The RIA058DS 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.

What is the knurled bead seat on the RIA058DS?
The 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.

What are the steel bushings in the RIA058DS?
Steel 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 RIA058DS.
