McLaren 540C/570S (2015-2020) Prepreg Dry Carbon Fiber Side Skirt

Engineered for McLaren 540C/570S Sports Series owners (2015-2020), this Prepreg Dry Carbon Fiber Side Skirt extends the side profile with downforce channels and aggressive character. Manufactured in Europe to factory-spec mounting tolerances and quality-controlled by BYC Performance, this McLaren 540C carbon side skirt bolts directly to OEM mounting points.

Optimized for the dihedral door + MonoCell II monocoque side profile, the skirt delivers both visual extension and high-speed underbody airflow management.

• Direct OEM Fit: Bolts to factory 540C/570S sill mounting points.

Prepreg (Dry) vs. Wet Carbon

Prepreg carbon is autoclave-cured under high heat & pressure, a more consistent weave, a controlled resin ratio — the production method widely chosen in motorsport.
