Maxton Design Side Flaps for Peugeot 208 GT Mk2
Give your 208 GT a sharper, lower look with these side flaps. They finish the line of the side skirts and add a clean, motorsport-inspired edge. Expect a neater airflow down the sides and a touch more stability at speed. They also help shield the lower doors from road spray and small debris.
Fitment
Designed for the Peugeot 208 GT Mk2, model years 2019-2023. These flaps fit only when paired with the matching Maxton Design side skirts for the 208 GT Mk2. Please use our vehicle lookup or see the Vehicle Fitment tab to confirm before ordering.
Materials and finish
Made from high-grade ABS plastic. This material is light, strong, and weather resistant. It is used by car makers for exterior trims because it handles heat and cold well and keeps its shape. UV-protected to help reduce fading over time.
What you get
- Left and right side flaps
- Fitting kit
Installation and safety
Supplied with model-specific hardware for a secure fit. Professional installation is recommended for best alignment with the side skirts. After fitting, check fixings regularly, especially after the first 100 miles. Be mindful of kerbs and ramps, as added width and lower edges can reduce ground clearance.
Note: These side flaps are intended to be installed with the corresponding Maxton Design side skirts for the 208 GT Mk2.
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.
