Mercedes-Benz CLS Sport / CLS63 Sedan Carbon Fiber Side Skirt Extensions 2014–2018

Carbon Fiber Side Skirt Extensions for Mercedes-Benz CLS Sedan

Give the lower side profile of your CLS a gloss carbon accent with these side skirt extensions. Designed to mount onto the vehicle's existing side skirts, they are exterior styling additions rather than complete replacement rocker panels or structural sill components.

Source-Listed Fitment

• Vehicle: Mercedes-Benz CLS Sedan.
• Model range listed together: CLS350, CLS400, CLS500, CLS550 Sport and CLS63 AMG.
• Years: 2014, 2015, 2016, 2017 and 2018.
• Exclusion: not for Base models.

The original title uses both W218 and C218, while the detailed fitment uses W218. Confirm the actual vehicle's chassis designation, production date, market specification and existing side-skirt profile by VIN and comparison before ordering. The combined model list does not establish that every trim, production update or model-year combination shares the same mounting surface.

Verify the actual Sport or AMG side-skirt configuration; an engine badge alone is not sufficient to confirm compatibility. This listing does not establish Shooting Brake fitment or compatibility with aftermarket replacement side skirts. Do not assume an excluded Base vehicle becomes compatible simply by fitting unrelated trim.

Construction and Finish

• Source-listed 3x3 weave carbon fiber.
• Glass fiber composite reinforcement is expressly described in the source.
• High-gloss lacquer with hand and machine polishing.
• Source-described double-layer UV-protected clear coating.
• Source-described development using 3D design, CNC moulding and trial installation on a vehicle.

This is carbon fiber with glass fiber composite reinforcement, not a documented all-carbon laminate. No dry-carbon or wet-carbon manufacturing method, laminate thickness, dimensions or measured net weight is supplied. Development and trial-fit descriptions do not guarantee identical fit on every listed vehicle. The UV-protected finish does not promise permanent fade resistance.

These extensions offer a visual styling change. No aerodynamic, downforce, drag, handling or fuel-economy test data is supplied, so measurable performance improvements are not promised.

Package and Mounting Details

The source lists side skirt extensions, installation tape and general supplied hardware. It does not itemize the physical piece count, a left/right coverage map, fastener quantities or individual mounting components. Plural wording alone does not establish an exact two-piece pair; confirm the supplied quantity and coverage before ordering.

The original description refers both to hardware-based mounting and to tape installation. Confirm how the tape and any mechanical hardware are intended to work together for this actual product. Tape inclusion does not establish that it is pre-applied or sufficient as the sole attachment method.

Professional Installation

1. Check the original side skirts for damage, loose clips or previous repairs. Trial-fit the supplied extensions before drilling or exposing adhesive.
2. Match each supplied piece to its intended position. Check the full mounting length, contours, end alignment and contact area without forcing the laminate.
3. Verify door movement, wheel clearance, drainage, lifting-point access and service access. Assess ground clearance over ramps, driveways and speed bumps, including relevant suspension heights.
4. Confirm the complete fastening procedure and suitable attachment points. Do not drill structural sills, wiring routes or concealed components without a verified procedure.
5. Prepare adhesive contact surfaces with compatible products and allow them to dry fully. Follow the specified adhesive's temperature, pressure and curing requirements.
6. Use the required hardware and specified tightening procedure without crushing or overtightening the laminate. No torque values or drilling pattern are supplied in this listing.
7. Check secure retention and clearance before driving, then inspect the attachment periodically and after any ground contact.

The source describes direct fitment without modification, but does not provide a complete mounting procedure to substantiate that for every listed configuration. Do not assume no drilling, no adjustment or installation within a fixed time. Professional fitting is recommended.

Do not drive with loose extensions, cracked mounting areas, protruding fasteners or interference with doors or wheels. These are not steps, jacking points or load-bearing sill reinforcements. Do not use them to support the vehicle or a person's weight.

Care

Use a soft cloth and non-abrasive cleaner compatible with the clear coat. Avoid strong solvents and high-pressure water directed at bonded edges. Allow any adhesive to cure according to its instructions before washing. Inspect the finish, laminate and mounting points regularly, especially after impacts or scraping.

Frequently Asked Questions

Will these fit Base models?
No. Base models are expressly excluded by the source.

Are these complete replacement side skirts?
No. The detailed description identifies extensions mounted onto the existing side skirts, not complete structural rocker panels.

Are they pure carbon fiber?
The source specifies carbon fiber reinforced with a glass fiber composite. An all-carbon construction is not established.

What weave and finish are specified?
3x3 weave, a high-gloss finish and double-layer UV-protected clear coating are listed.

Are exactly two pieces included?
The source does not provide a physical piece count or detailed left/right packing list. Confirm actual contents before ordering.

Can I fit them with tape alone?
The source mentions tape and general hardware without defining the complete attachment method. Verify the required retention system rather than assuming tape alone is sufficient.

Do they improve aerodynamic performance?
No supporting aerodynamic measurements are supplied. This listing makes no quantified performance claim.
