BMW M5 F90 Prepreg Dry Carbon Fiber Front Fender Set

Engineered for BMW M5 F90 owners who want significant weight savings and a premium motorsport side profile, this Prepreg (Dry) Carbon Fiber Front Fender Set (left + right pair) is the carbon-fiber version of the OEM steel fender. Manufactured in Europe to factory-spec mounting tolerances and quality-controlled by BYC Performance, this BMW M5 F90 carbon fender set bolts directly to OEM mounting points — no cutting, no drilling, no modification required.

If you're building a serious BMW M5 F90 tuning project and need a part that exceeds the OEM steel fender in weight and finish, this dry carbon front fender set is built for you. Autoclave-cured prepreg carbon fiber is noticeably lighter than wet-lay parts, offers very high strength for its weight, and delivers outstanding UV resistance. Engineered to complement the aggressive character of the S63B44T4-powered F90 M5 — 600 hp standard and 617 hp Competition.

Key Features

• Prepreg (Dry) Carbon Technology: Pre-impregnated carbon plies cured in an autoclave under high heat and pressure ensure a consistent weave.
• Matched L+R Pair: Symmetric carbon weave on left and right fenders, supplied together as a set.
• Weight Saving: Noticeably lighter than the OEM steel fender.
• Race-Grade Strength: Carbon fiber offers very high strength for its weight.
• OEM Profile: Vent-free classic fender profile — for owners who prefer a cleaner side view.
• 2x2 Twill Carbon Weave: Authentic carbon fiber pattern under a high-gloss UV-protective clear coat.
• Direct OEM Fit: Plug & play installation on factory F90 M5 (pre-LCI) fender bolt locations. Includes OEM side-marker housing cutout.

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 — leaving air voids and inconsistent weight. Prepreg (dry) carbon:

• Cured in an autoclave under high heat and pressure → a more consistent weave
• A controlled resin ratio → lighter and stronger
• The production method widely chosen in motorsport
• Minimal UV fading over years of use
