BMW M3 F80 / M4 F82 Prepreg Dry Carbon Fiber MP Side Skirts
Engineered for BMW M3 F80 and M4 F82 owners, this Prepreg (Dry) Carbon Fiber MP Side Skirt set adds M Performance-grade aggression to your side profile while cleaning up airflow. Imported from leading manufacturers around the world and quality-controlled by BYC Performance, this BMW F80 / F82 carbon side skirt bolts directly under the OEM skirt with no cutting. Sold as a left + right pair.
If you're building a BMW M3 F80 tuning or M4 F82 modification project and want OEM M Performance styling in quality carbon, this dry carbon MP side skirt set is the answer. Autoclave-cured prepreg carbon fiber is noticeably lighter than wet-lay parts, with superior strength and outstanding UV resistance. Designed to match the aggressive character of the S55B30T0-powered previous-generation M3/M4 family (425 hp standard, 444 hp Competition, 460 hp CS, 493 hp GTS).
Key Features
- Prepreg (Dry) Carbon Technology: Pre-impregnated carbon plies autoclave-cured under high heat and pressure; homogeneous resin.
- M Performance Styling: Carbon version of the OEM F80/F82 MP side skirt, noticeably lighter than the factory plastic part.
- Race-Grade Strength: Carbon fiber offers very high strength for its weight; resists stone chips and curb contact.
- Aerodynamic Performance: Manages side airflow, reduces turbulence, improves high-speed lateral stability.
- 2x2 Twill Carbon Weave: Authentic pattern under high-gloss UV-protective clear coat.
- Left + Right Matched Set: Pair packed from the same batch for color and weave consistency.
- Direct OEM Fit: Plug & play on factory F80 sedan and F82/F83 coupé/convertible side skirts.
Prepreg (Dry) Carbon vs. Wet Carbon: Which Is Better?
Most aftermarket carbon parts are made using wet lay-up, where resin is applied by hand and cured at room temperature, which can leave air voids and inconsistent weight. Prepreg (dry) carbon:
- Cured in an autoclave under high heat and pressure → a more consistent weave
- Controlled resin ratio → lighter and stronger
- The production method widely chosen in motorsport
- Minimal UV fading over years of use
Installation Notes
Installing the BMW F80 / F82 MP carbon side skirts uses screws into the OEM skirt and/or 3M tape:
- Raise the vehicle and clean the lower skirt surface (alcohol or silicone remover).
- Test-fit the new carbon extension along the OEM skirt.
- Secure to OEM mounting points with supplied hardware to the manufacturer's recommended torque.
- If 3M tape is supplied, apply and maintain pressure for at least 24 hours.
- Confirm left/right symmetry: ground-to-skirt gap should be equal.
Care & Maintenance
Wash with pH-neutral car shampoo. Apply carbon-safe sealant every 6 months. Keep pressure washer nozzle at least 30 cm from the surface.
