BMW M5 F90 | Prepreg Dry Carbon Fiber MP Front Lip Splitter

BMW M5 F90 Prepreg Dry Carbon Fiber MP Front Lip Splitter

Engineered for BMW M5 F90 owners inspired by the M Performance catalog, this Prepreg (Dry) Carbon Fiber MP Front Lip Splitter adds a sharp, aggressive extension to your sedan's front bumper while contributing to front-axle aero. Made to factory-spec mounting tolerances by leading manufacturers around the world and quality-controlled by BYC Performance, this BMW M5 F90 carbon front lip bolts directly to OEM bumper clip and bolt points, no cutting, no drilling, no modification required.

If you're building a serious BMW M5 F90 tuning project and need a part that brings M Performance character to the factory bumper, this dry carbon front lip is built for you. Autoclave-cured prepreg carbon fiber is noticeably lighter than wet-lay carbon parts, offers very high strength for its weight, and delivers outstanding long-term UV resistance. Engineered to match the aggressive character of the S63B44T4-powered F90 M5, 600 hp standard and 617 hp Competition, this lip is the ideal aesthetic and functional upgrade for both highway and track use.

Key Features

• Prepreg (Dry) Carbon Technology: Pre-impregnated carbon plies cured in an autoclave under high heat and pressure ensure a consistent weave.
• M Performance Styling: Prepreg carbon version of the OEM F90 M5 MP front lip design. Adds a sharp extension to the factory bumper.
• Front-Axle Aero: Optimized lip profile directs airflow at the front end at high speed and contributes to throttle response.
• Race-Grade Strength: Carbon fiber offers very high strength for its weight. Resists stone chips and light curb contact.
• 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) bumper clip and bolt points.
• UV & Chemical Protection: Long-life clear coat protects against fading, cracking, fuel splash, and road tar.

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

Installation Notes

Installing the BMW M5 F90 carbon front lip is a direct add-on to the lower face of the bumper. Professional installation is recommended:

1. Clean the lower bumper surface with isopropyl alcohol and dry.
2. Test-fit the carbon lip dry (center alignment is critical, equal gap left/right).
3. Secure with supplied 3M double-sided tape or hardware kit.
4. If using screws, fasten to OEM under-bumper clip points to the manufacturer's recommended torque.
5. Check ground clearance below the lip; take extra care over curbs and steep ramps.

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. Avoid curb scrapes: the front lip becomes the lowest point of the vehicle.
