BMW M5 F90 | Prepreg Dry Carbon Fiber CS Hood

BMW M5 F90 Prepreg Dry Carbon Fiber CS Hood

Engineered for BMW M5 F90 owners inspired by the limited-edition M5 CS aesthetic, this Prepreg (Dry) Carbon Fiber CS Hood brings aggressive motorsport character to the front of your sedan while significantly improving engine bay heat extraction. Made to factory-spec hinge and latch tolerances by leading manufacturers around the world and quality-controlled by BYC Performance, this BMW M5 F90 CS carbon hood 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 want to bring the limited-production 635 hp M5 CS look to your standard F90 M5, this dry carbon CS hood is built for you. Autoclave-cured prepreg carbon fiber is noticeably lighter than the OEM steel hood, more structurally consistent, and offers outstanding long-term UV resistance. Integrated heat extractor vents pull hot engine bay air out, essential for the S63B44T4 600-635 hp V8.

Key Features

• Prepreg (Dry) Carbon Technology: Pre-impregnated carbon plies cured in an autoclave under high heat and pressure ensure homogeneous resin distribution and a consistent weave.
• M5 CS Styling: Carbon fiber reinterpretation of the limited-edition 2022 M5 CS hood design. Brings CS character to standard F90 M5.
• Significant Weight Savings: Noticeably lighter than the OEM steel hood. Reduced front axle weight sharpens steering feel.
• Integrated Heat Extractor Vents: Extracts hot V8 engine bay air, critical for sustained driving and track sessions.
• Race-Grade Strength: Carbon fiber offers very high strength for its weight. Resists stone chips and light 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) hinges, latches, and hoses.
• 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 CS carbon hood is a direct replacement of the factory hood. Professional installation is recommended:

1. Disconnect the washer fluid hoses and remove the OEM hood insulation pad.
2. Loosen the hinge bolts; with two people, lift off the old hood.
3. Align the new CS carbon hood to the hinges and bolt in place.
4. Verify panel gaps; fine-tune hinge position if needed.
5. Important: Because the carbon hood is significantly lighter than the steel hood, the OEM gas struts may not hold the hood fully open. Upgraded carbon-hood-spec gas struts are recommended.
6. Reconnect the latch mechanism and washer fluid hoses.

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. Periodically clear leaves and debris from heat extractor vents.

FAQ

Does this fit the F90 LCI (2021+)?
No. The F90 LCI facelift has different front panel and headlight geometry. M5 F90 LCI owners should contact BYC for hood availability.

Compatible with both standard M5 and M5 Competition?
Yes. This hood fits both 2018-2020 standard M5 F90 (600 hp) and 2019-2020 M5 Competition F90 (617 hp). Hood geometry is identical across pre-LCI F90 trims.

Is this the original hood from the limited-edition M5 CS?
No. This is an aftermarket carbon hood inspired by the 2022 M5 CS design. It brings CS visual character to the standard F90 M5 and M5 Competition.

Is this the same as the BMW M5 F10?
No. M5 F10 (2011-2017) is the previous generation with different hood length and hinge position. A separate carbon hood for the F10 is available.

Does it fit BMW M3 F80 / M4 F82?
No. M3 F80 and M4 F82 have different chassis and hood geometry. Separate F-series M3/M4 carbon hoods are available.

Will the OEM gas struts hold up the carbon hood?
Often not: the carbon hood is significantly lighter, so OEM struts may overshoot or fail to fully open. Upgraded carbon-spec gas struts are recommended.

Will rain damage dry carbon parts?
No. Autoclave-cured prepreg carbon is fully waterproof and weather-resistant.
