Does the Rear Diffuser for 992 GT3 RS also fit the 992.2 GT3?

Yes. Kline Innovation lists this Rear Diffuser for 992 GT3 RS cars from 2022 onward and for the facelifted 992.2 GT3 from 2025 onward. The earlier 992.1 GT3, built from 2021 to 2024, takes a different Kline diffuser, which Bulletproof Automotive lists separately. Owners unsure of their model year can contact the team before ordering.

Which version has the checkered carbon pattern?

The Textreme version has the wide checkered pattern. Textreme is a spread-tow carbon fabric woven from flat tapes, so it forms broad squares instead of the tight diagonal lines of a two-by-two twill. The F1 grade version is the two-by-two twill. Shape, fitment and construction are otherwise the same, and Textreme carries the higher price.

Was the diffuser developed with aerodynamic testing?

Yes. Kline Innovation checked the diffuser shape with computational fluid dynamics during development, as it did for its carbon wing for the GT3. Kline does not publish a downforce figure for the diffuser itself, so the gain cannot be quoted as a number. It is best seen as a functional carbon upgrade matched to the rest of the Kline aero program.

How much does the Textreme diffuser weigh?

Kline Innovation quotes the Textreme diffuser at about 5.3 lbs, or 2.4kg. No separate weight is published for the F1 grade twill version, though both are made from autoclave-cured pre-preg carbon in the same molds. For a part that spans the full width of the rear bumper, that is a light piece of bodywork.

How is the finish different from other carbon diffusers?

Kline Innovation skips the thick clear lacquer found on many carbon parts and polishes its cured carbon to a gloss instead, an approach Kline compares to the finish on Koenigsegg carbon parts. The thinner surface keeps the weave crisp, which matters most on the Textreme version, where the checkered squares are the main visual feature.

Description

Kline Innovation Carbon Rear Diffuser for 992 Porsche 911 GT3 RS and 992.2 GT3

Kline Innovation’s Carbon Rear Diffuser for 992 Porsche 911 GT3 RS and 992.2 GT3 covers the two cars Kline groups under one design: the GT3 RS from 2022 and the facelifted GT3 from 2025. It is built in Kline’s Romanian workshop from F1 grade pre-preg or Textreme carbon, cured in an autoclave inside CNC-machined molds and developed with computational fluid dynamics alongside the rest of the Kline 992 aero program. On a car as purposeful as the RS, this is a detail that rewards a close look.

Construction

The two material options look nothing alike. The F1 grade diffuser is a classic 2×2 twill. The Textreme diffuser is the one with the wide checkered pattern: its spread-tow fibers are flattened into thin tapes before weaving, so each square is broad and the surface lies flat with very little crimp. Kline points to the use of Textreme in Formula 1 and aerospace work, and quotes the Textreme diffuser at about 5.3 lbs (2.4kg).

Features

F1 grade pre-preg carbon fiber in a 2×2 twill weave
Optional Textreme pre-preg spread-tow carbon with a checkered weave
Autoclave cured in molds Kline designs in CAD and machines on CNC equipment
Full-width row of vertical carbon strakes
Gloss polished finish without a thick lacquer layer

Applications

Porsche 911 GT3: 992.2 | 2025-present | 4.0L flat-six
Porsche 911 GT3 RS: 992 | 2022-present | 4.0L flat-six

Notes

About Kline Innovation

Kline Innovation builds exhaust systems and carbon fiber components in Romania, with every stage of a project carried out in its own workshop: laser scanning, CNC laser cutting, mandrel bending, welding, milling and autoclave curing of carbon parts. The company works in Inconel, titanium, 304 stainless steel and carbon fiber, and its exhausts made their name in the Porsche community before moving on to Ferrari, Lamborghini, McLaren and other exotics. Low-volume makers including RUF, W Motors and Corbellati are among its clients, and Kline names itself the official exhaust supplier to Lando Norris.

Additional Information

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. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

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.
