Does the Carbon Rear Bumper Diffuser require any change to the exhaust?

No. The diffuser is cut to frame the factory RS Q8 exhaust outlets in their original positions, so no exhaust modification is involved. If you later fit an aftermarket system with different outlet sizes or spacing, confirm clearance with the exhaust manufacturer before ordering.

Will it fit a 2019 to 2024 RS Q8?

No. Audi changed the rear bumper at the facelift and this diffuser is cut for the later shape. Urban sells a different rear treatment for the earlier car. Check your build year first, because the two do not interchange.

Is this visual carbon or structural carbon?

Visual carbon. The weave is the visible finish rather than a load-bearing layup, chosen to match the factory carbon options. It is bought for appearance, not for downforce or weight saving, and it should not be expected to change how the car behaves.

Does fitting need cutting or drilling?

No. The diffuser mounts to factory locations with no cutting of original bodywork. As with any hand-finished carbon panel, trial-fit it and check the gaps along the bumper edge before committing to a permanent fixing.

Should I fit the diffuser or the spoilers first?

The diffuser carries more of the visual change at the rear than either spoiler, so it is the usual first step when a build is being staged. Owners who want the complete treatment generally find the eight-piece kit cheaper than buying the components one at a time.

Description

Urban Automotive Visual Carbon Rear Bumper Diffuser for 4M Audi RS Q8 (Facelift)

Urban Automotive’s Carbon Rear Bumper Diffuser for the facelift 4M Audi RS Q8 replaces the plain lower section of the revised rear bumper with a deep strake-detailed panel that frames the factory exhaust outlets. It is produced in the same satin OEM Audi weave as the rest of the range, matched to Audi’s own carbon packages in pattern and sheen. The diffuser is the part that does most of the visual work at the rear of this car, and it is worth fitting before the spoilers if the budget is being staged.

About Urban Automotive

Urban Automotive is a UK-based vehicle modification specialist founded in 2013 with a focus on luxury and performance SUVs. Built around an “OEM plus” design philosophy, the company develops and manufactures its own components in-house rather than reselling third-party parts, giving them direct control over design, tooling, material selection, and final finish. Their carbon fiber work is produced at their UK facility, and wheel collaborations series are finished by hand in Miami. The clientele is predominantly Range Rover, Defender, and G-Wagen focused, with each build configured individually rather than sold as a fixed kit off a shelf. Urban has become one of the more recognized names in the high-end SUV modification space, largely because the work tends to read as factory-coherent rather than aftermarket-obvious.

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.
