Maxton Design Full Body Kit for BMW X4 M (F98) Facelift
Give your X4 M a sharper, more purposeful look with a kit designed to fit like factory parts and stand up to daily use.
This kit fits BMW X4 M F98 Facelift models from 2021 onwards. It is compatible with vehicles fitted with a towbar. For best results, use our vehicle lookup to confirm fitment or check the Vehicle Fitment tab.
What you get
A complete styling package engineered for the F98:
– Front splitter, side skirt diffusers, rear splitter with vertical bars, bottom spoiler cap 3D, and upper spoiler cap.
Material and finish
Made from ABS plastic, the same type used for many OEM bumpers. It offers good impact resistance and flexibility, so it copes well with road use. Supplied in Gloss Black for a clean, premium finish. Material holds a TUV MATERIALGUTACHTEN certificate for quality assurance.
Why fit this kit
It lowers the visual profile, adds width to the stance, and helps guide airflow around the car. You get a sportier look without compromising everyday practicality.
Fitment notes and safety
– Side skirt diffusers are supplied without holes for the factory carpet light. You can add holes yourself, but this may cause light refraction.
– We recommend professional installation and careful test fitting before final mounting.
– Clean all surfaces and use the supplied hardware or high-quality fixings rated for automotive use. Check fasteners periodically.
Care
Wash with mild shampoo and a soft cloth. Avoid aggressive chemicals and abrasive pads to protect the Gloss Black finish.
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.
