Thermoformed ABS Side Skirts Diffuser Splitter Extension fits for Mercedes-Benz C-class Coupe AMG-Line C204/Estate AMG-Line S204 Facelift/Sedan AMG-Line W204 Facelift 2011-2015

▎Fitment & Compatibility

These side skirts are designed specifically for the 2011, 2012, 2013, 2014, 2015 Mercedes-Benz C-Class in AMG-Line (AMG Line) specification, following the AMG-Line rocker line for a precise, vehicle-matched fit. One set covers three body styles:

●Coupé — C204, AMG-Line

●Estate / Wagon — S204, AMG-Line, facelift

●Sedan — W204, AMG-Line, facelift

For distributors this means one part number serves your entire 2011-2015 C-Class AMG-Line customer base, instead of stocking a body-style-specific SKU.

Please check before ordering: standard (non-AMG-Line) C-Class, and pre-facelift W204 / S204 sedan and estate, are not covered by this SKU. Send us your model year, body style and a photo of your current rocker panel — we confirm fitment in writing before the order is processed.

▎Material & Craftsmanship

Manufactured from high-quality thermoformed ABS (vacuum-formed ABS), this Mercedes-Benz C-Class side skirt offers excellent flexibility, durability and impact resistance for everyday driving conditions. ABS flexes and absorbs kerb and car-park impacts instead of shattering, does not rust, and will not develop the fibre bloom or stress cracks associated with fibreglass kits.

▎Design & Appearance

Designed to extend the lower profile of the vehicle, these side skirts give the C-Class AMG-Line a lower, wider and more aggressive stance while enhancing its overall aerodynamic look. Supplied in [TBC: primer black / matte black] and ready for prep and topcoat, so your paint shop can colour-match any OEM Mercedes-Benz paint code.

▎Installation

This C-Class side skirt set is designed for straightforward installation using automotive-grade double-sided adhesive tape and/or mounting screws, providing a secure fit without complicated, heavy modifications to the original bodywork.

▎Packing & Delivery

▎FAQs about Mercedes-Benz C-class Coupe AMG-Line C204 S204 W204 Facelift Car Side Skirt Diffusers

Q: Which Mercedes-Benz C-Class models does this side skirt fit? 

A: It fits the 2011-2015 C-Class in AMG-Line (AMG Sport) specification, across three body styles: Coupé (C204), Estate / Wagon (S204, facelift) and Sedan (W204, facelift). It is not a universal part. 

Q: What material is used, and what are its key advantages? 

A: It is made from high-quality ABS (Acrylonitrile Butadiene Styrene) sheet, vacuum-formed (thermoformed) over a mould. Forming from flat sheet keeps the material thickness uniform along the full length of the panel, and on a side skirt well over a metre long that is what makes the part sit flat against the sill instead of lifting at one end. Sheet-forming tooling also costs far less than a full injection tool for a part this size, which is what keeps the minimum order quantity realistic when you open a new body style. HAOSHENG does not manufacture real carbon fibre, and we will not describe an ABS part as carbon fibre.

Q: Is it an add-on over the original sill, or a full replacement? 

A: This is an add-on part: it fits over the original side sill and the original cover stays in place. Fitting is done with automotive-grade double-sided adhesive tape together with the supplied self-tapping screws at the original fixing points — no cutting and no welding of the body.

Q: Will it change ground clearance, or catch on speed bumps and in a car wash? 

A: It sits lower than the standard sill — that is the point of the part — so on a car that is already lowered, or one regularly driven over high kerbs, it will be the first thing to make contact. This is a styling part: we make no downforce or aerodynamic claim. For washing, hand wash or a touchless wash; a brush-type automatic wash is hard on any dark exterior trim.

Q: What surface finishes are available?

A: Options include Unpainted/Primer (ready for custom color matching), Glossy Black, and Carbon Fiber Look.

Q: Can I order a sample before placing a bulk order?

A: Yes, sample orders are available for quality evaluation and test fitting. Contact our sales team directly for MOQ requirements and volume discounts.

Q: How is the product packaged for export shipping?

A: Each unit is packaged in reinforced export-grade cartons with protective cushioning, making it ideal for Amazon/e-commerce drop-shipping as well as full container ocean freight.

Q: Are you a direct manufacturer, and do you support custom branding or mixed container orders?

A: We are the source factory—Changzhou Haosheng Vehicle Parts Co., Ltd.—located in Changzhou, China. Buying factory-direct eliminates trading markups. We support mixed-SKU container shipments, custom private-label packaging, and sample orders for fitment verification.

Q: What if the item arrives damaged, is shipped incorrectly, or cannot be installed?

A: Please contact us within 7 days of receiving the goods. We cover the following three situations:

  · Wrong item shipped

  · Product that cannot be installed

  · Damage caused during transport

Products that have already been installed or used are not covered.
