What vehicles does the BBS FI-R Centerlock wheel in 20x11.5 +54 fit?

This wheel is the rear fitment for the 991.2 Porsche 911 Turbo and 911 Turbo S built from 2017 to 2019, on the factory centerlock hub. It will not mount to a five-lug Porsche hub. Owners of other centerlock 911 models should confirm offset and caliper clearance before ordering, particularly where an aftermarket brake kit is fitted.

Is the FI-R forged or cast?

Forged. BBS die-forges the FI-R from a single billet of aluminum under up to 18 million pounds of pressure, producing a one-piece monoblock with no bolts or welds. Forging removes the internal porosity that casting leaves behind, which is what allows the rim section to be made thinner and lighter without losing strength.

How much does the 20x11.5 FI-R weigh?

20.7lbs, or 9.4kg. For a 20 inch wheel 11.5 inches wide that figure is low, and it is the reason the BBS FI-R Centerlock is specified on 911 Turbos that already have the power. Lower rotating mass eases the load on the brakes and drivetrain, and lower unsprung mass gives the dampers less to control.

Is this sold as a single wheel or a set?

Single. The price covers one 20x11.5 +54 rear wheel in Diamond Black. A staggered set for the 991.2 911 Turbo needs two of these rears plus two 20x9 +52 fronts, so four wheels in total. Order the quantity that matches the fitment before checking out.

Will factory TPMS sensors work in this wheel?

Yes. The FI-R is machined to accept the OEM Porsche TPMS sensor, so the existing sensors can be transferred from the factory wheels during mounting. Sensors are not supplied with the wheel. Have the tire shop check sensor condition and battery life while the wheels are apart.

What is the center bore and bolt pattern?

The wheel uses the Porsche 1-130 centerlock interface with a 62.5mm center bore, which means a single central nut rather than five studs. No spacers or adapters are needed or recommended. Centerlock nuts must be torqued to the factory figure with the correct socket every time the wheel is removed.

Description

BBS FI-R Centerlock Diamond Black Wheel (20×11.5 +54) for 991.2 Porsche 911 Turbo

The BBS FI-R Centerlock wheel brings five decades of race-bred wheel engineering to the 991.2 911 Turbo. BBS has supplied Formula 1 and DTM grids since the 1970s, and the FI-R is built on the same die-forging process the company developed there: a single billet of aluminum pressed into a monoblock whose grain structure follows the finished shape of the wheel rather than running straight through it. At 20.7lbs in 20×11.5, it strips rotating and unsprung mass from the rear axle, where a 911 Turbo reports the difference immediately through steering weight, ride quality and how quickly the rear settles after a crest. The Diamond Black finish keeps all of that engineering understated.

Forged Construction

BBS die-forges the FI-R under up to 18 million pounds of pressure, using either 6000 series aluminum or the company’s own magnesium alloy depending on the application. Forging closes the porosity that casting leaves behind and aligns the grain along the load paths the wheel actually sees, so the rim section can be made thinner without giving up strength. There are no bolts, no welds and no joint to fatigue, because the spokes, hub face and barrel are one piece of metal.

Weight and Design

Each cross spoke carries a relief hole that removes material from a low-load area, and the back faces are milled to the minimum section the structure needs. A 20×11.5 wheel of this width arriving at 20.7lbs is the whole point of the Forged Line: less rotating mass for the brakes and drivetrain to manage, and less unsprung mass for the dampers to control over broken pavement.

Centerlock Fitment

This is a true centerlock wheel, machined for the single-nut hub Porsche fits to the 911 Turbo rather than adapted from a five-lug pattern. The +54mm offset places the 11.5 inch rear where the factory arch expects it, so the staggered stance stays faithful to the car’s proportions. A matching 20×9 +52 front completes the set.

About BBS

In 1970, two race car enthusiasts from Schiltach in Germany, Heinrich Baumgartner and Klaus Brand, founded BBS to build lightweight fiberglass body panels that gave teams an advantage on track. BMW Motorsport noticed, and the company grew quickly. In 1983 BBS introduced the three-piece RS wheel, a design still regarded as one of the best ever made. The company remains committed to its founding idea: Technology through Motorsport.

BBS builds wheels for cars, trucks and SUVs across three ranges. The Forged Line covers one-piece and two-piece forged designs, the Performance Line covers one-piece and dual-construction flow formed models, and the Design Line covers low pressure cast rims. Design, engineering and manufacturing all happen in house, which is how BBS keeps its original equipment programs and its motorsport programs feeding each other.

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
