Maxton Design Carbon Fibre Spoiler for Mercedes-AMG GT R (C190) Facelift
What it does
Add stable rear downforce, sharpen high-speed stability, and give your AMG GT a factory GT R look. The design mirrors the GT R geometry to help the car feel planted without excess drag.
Fitment and compatibility
Fits Mercedes-AMG GT R C190 Facelift 2017-2023. Also compatible with AMG GTC, AMG GTS and AMG GT of the same era, but you must first install the AMG GT R spoiler base. Use the vehicle lookup on our site or check the Vehicle Fitment tab to confirm.
Materials and build
Made by Maxton Design Carbon Division using Pre-preg carbon fibre. Hand layered 245 g twill in a 2/2 weave, set at 90 degrees for strength and a clean finish. Cured at high pressure to reduce impurities and increase stiffness. The low weight helps maintain performance and balance.
What you get
- Carbon wing spoiler
- Carbon lower spoiler mounts
- Aluminium mounting brackets
- Carbon boot lid mounts
- Carbon wing end risers
Installation and safety
For best results, use a professional installer. Check alignment, torque all fasteners to spec, and inspect fixings after the first 100 miles. Ensure the boot lid structure and GT R base (if retrofitting to GT, GTS or GTC) are correctly prepared. Avoid over-tightening to protect carbon layers. Periodically check hardware for security.
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.
Returns
Purchased the incorrect kit for your vehicle? Or not sure you like the surface finish when it arrives? No problem!
Maxton Design products are eligible for return if the product has not been fitted, drilled, modified or damaged in any other way and still has the protective factory film intact. Unfortunately, there are no exceptions, this applies to fully removed and partially removed films.
Products with a protective film in place are clearly marked with this sticker, if you believe there to be an issue with the product but you can't tell without removing the film, please contact our support team directly for assistance.
DO NOT REMOVE THE FACTORY FILM UNTIL YOU'VE LINED IT UP, AND YOU'RE READY TO FIT THE PART.

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.
Fibreglass & "Non-Prepped" Products
By adding these products to your basket you are agreeing to the below statement.
All Maxton Design Fibreglass products including certain bumpers, spoilers, spoiler extensions and skirts will require “prep” before installing.
These are not a simple 'ready to fit' modification. 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.
Product images shown for sale often indicate a finished product, the colour shown on the vehicle is for illustration purposes.
