Mercedes-Benz AMG CLA C118 | Prepreg Dry Carbon Fiber Side Skirt Add-on

Mercedes-Benz AMG CLA C118 (2019+) Prepreg Dry Carbon Fiber Side Skirt Add-on

Designed for Mercedes-Benz AMG CLA C118 second-generation (2019+) owners, this Prepreg Dry Carbon Fiber Side Skirt Add-on is an extension that bonds beneath the stock skirt, preserving the existing skirt while extending the side profile with a carbon detail. Made to factory-spec tolerances by leading manufacturers around the world and quality-controlled by BYC Performance, this CLA C118 carbon side skirt add-on attaches to the stock skirt edge with 3M double-sided tape + clips.

This is the add-on extension version. The stock skirt stays in place, the add-on is fitted over it. If you're looking for a full replacement skirt that takes the place of the stock part, see our sister SKU CLA C118 Side Skirt. This add-on is ideal for owners who want the aggressive AMG side profile while preserving the original car structure.

Key Features

• Prepreg (Dry) Carbon Technology: Autoclave-cured under high heat and pressure; a more consistent weave.
• Add-on Extension Design: Bonds to the stock skirt edge, doesn't replace the whole skirt. Reversible.
• AMG-Inspired Detail: Adds CLA45 S AMG-style lower-profile aggression to the stock skirt.
• 3M Tape + Clip Install: Automotive-grade 3M VHB tape + OEM clip points. No drilling or cutting.
• Race-Grade Strength: Very high strength for its weight; resists stone chips and light side-contact.
• 2x2 Twill Carbon Weave: Authentic carbon look under high-gloss UV-protective resin.
• Left + Right Pair: Ships as a left + right pair.

Prepreg (Dry) Carbon vs. Wet Carbon

Most aftermarket carbon parts use wet lay-up. Prepreg (dry) carbon is autoclave-cured under heat and pressure, offers a more consistent weave, a controlled resin ratio, and is lighter. The production method widely chosen in motorsport.

Side Skirt Add-on vs. Full Side Skirt: What's the Difference?

Our catalog includes two CLA C118 side-skirt products:

• Side Skirt Add-on (this product): An add-on extension bonded to the stock skirt edge. The stock part stays in place; the add-on is fitted over it. Lighter, reversible.
• Side Skirt (full): A full replacement part that takes the place of the stock skirt. More aggressive look, more involved install.

Choose the add-on to preserve the stock skirt and add a subtle carbon accent.

Installation Notes

DIY-capable; professional support recommended:

1. Wipe the stock skirt edge with isopropyl alcohol (bonding surface must be clean).
2. Remove the 3M tape liner (only at the moment of bonding).
3. Align the carbon add-on to the skirt edge, seat the clip points.
4. Press firmly. Avoid washing for 24 hours for full bond.
5. Repeat for the opposite side.

Care & Maintenance

Wash with pH-neutral shampoo. After track use, wipe with a carbon-safe cleaner. Apply carbon sealant every 6 months.

FAQ

Compatible with CLA C117?
No. C117 and C118 have different side-profile geometry.

Difference between Add-on and full Side Skirt?
This add-on bonds to the stock skirt. The full skirt replaces the stock part. Choose the add-on to preserve the stock skirt, the full skirt for an aggressive replacement.

Does the 3M tape hold in the heat?
Yes. Automotive-grade 3M VHB tape holds across a wide temperature range; daily, wash, and track use are fine.

Can it be removed later?
Yes, it can be removed with a heat gun + plastic pry tool. Far more reversible than the full replacement.
