Maxton Design Pre-preg Carbon Fibre Rear Diffuser – Audi RS 6 (C8) Towbar Version
Designed for the Audi RS 6 C8, this towbar-compatible rear diffuser adds a sharper, more purposeful look and helps clean up airflow at the rear. It is shaped to clear the factory tow hitch while keeping ground clearance sensible.
Built from Pre-preg carbon fibre for high strength and low weight. Each piece is hand laid using 245 g twill in a 2/2 90° weave, then cured under high pressure for a smooth, consistent finish.
Fits Audi RS 6 C8 models from 2019 to 2023. For best results, use our vehicle lookup or check the Vehicle Fitment tab to confirm compatibility with your exact car and towbar setup.
- Towbar compatible – profiled for factory hitch clearance
- Lightweight Pre-preg carbon fibre construction
- Durable high-gloss finish with visible 2/2 twill weave
Intended as a styling and aero aid. Expect a subtle reduction in rear turbulence and a more stable feel at speed, depending on vehicle setup.
Materials and build
Pre-preg carbon fibre is pre-impregnated with resin for precise fibre-to-resin balance. This process reduces excess weight and improves strength. High-pressure curing helps remove air pockets for a cleaner surface and better durability.
Installation and safety
Professional fitting is recommended. Ensure all fixings are tightened to the correct torque and recheck after initial use. Confirm adequate clearance around the towbar and exhaust. Do not use the diffuser to support towing loads.

Choosing a Kit
Our vehicle registration lookup system cannot detect factory trim level. It is important for customers to check the specification of their own vehicle against the product description, and if their vehicle has an existing sports trim level, body kit or factory enhancement that may cause it to look different from other similar models.
For example: Volkswagen R-Line, BMW M-Power/M-Pack, Audi S-Line, Ford ST-Line, Merc AMG-Line, Seat FR.
These kits will not fit models that don't meet these specifications.

Installation & Fitting
Instructions & Guides
Maxton Design provide either an online reference (below) or printed instructions with their products, we can't stress enough how important it is to follow these guidelines. Not only does this create a safe, aesthetically well fitted product, but it increases the longevity and lifespan of the kit.
Neither Progressive Parts nor Maxton Design will be able to provide and support or warranty for products fitted incorrectly. For example, front splitters require the front bumper to be removed, without doing so the bolts will be incorrectly positioned and may not be able to cope with the down-force exerted on it. Straying from the guidelines in this manner must be done so at the owners risk.

In transit, the items may get chipped or marked and as such prior to painting it is important you understand that the parts may require filling, sanding and repairing (defined "prep") prior to paint being applied, which can be undertaken by any reputable body shop at minimal cost.
Return requests based on not anticipating the definition above are not accepted, please be aware you have agreed to this statement and the definition of “prep” work required prior to purchasing.
