BMW M3 G80 / M4 G82 | Prepreg Dry Carbon Fiber Hood Fin

BMW M3 G80 / M4 G82 Prepreg Dry Carbon Fiber Hood Fin

Engineered for BMW M3 G80 and M4 G82 owners who want a real aerodynamic detail rather than pure decoration, this Prepreg Dry Carbon Fiber Hood Fin (canard) sits vertically on top of the hood and helps manage high-speed airflow over the bonnet. Autoclave-cured by leading manufacturers around the world and quality-controlled by BYC Performance, this BMW G80 / G82 carbon hood fin mounts cleanly with 3M VHB industrial tape: no drilling required.

If you're building a serious BMW M3 G80 tuning or M4 G82 modification project and want a part that adds DTM/GT3-inspired motorsport character while reducing front-axle lift at speed, this dry carbon hood fin delivers. Designed to match the S58-powered current-gen M3/M4 family (473-543 hp). Compatible with the M3 G80 Sedan, M4 G82 Coupé and M4 G83 Convertible hood contour.

Key Features

• Prepreg Dry Carbon Technology: Cured under high heat and pressure in an autoclave for a more consistent weave.
• Aerodynamic Function: Reduces high-speed lift over the hood and contributes to front-axle downforce.
• Motorsport Look: Vertical fin design inspired by M Motorsport DTM/GT3 cars.
• Easy Installation: 3M VHB industrial adhesive tape mount, no drilling needed.
• 2x2 Twill Carbon Weave: Authentic carbon pattern under a UV-protective high-gloss clear coat.
• OEM Hood Contour Fit: Direct fit to G80 Sedan and G82/G83 Coupé/Convertible hood curvature.
• UV & Chemical Protection: Resists fading and bug/tar splash.

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 G80 / G82 carbon hood fin takes about 30 minutes:

1. Open the hood; clean the mounting area with isopropyl alcohol.
2. Dry-fit the fin and mark its position.
3. Remove the 3M VHB tape backing.
4. Press the fin firmly onto the marked position.
5. Avoid washing for 24 hours; full adhesive cure takes 72 hours.

Care & Maintenance

Wash with pH-neutral car shampoo. Because of the adhesive tape, keep pressure washer nozzle at least 30 cm from surface and at a low angle. Apply carbon-safe sealant every 6 months.
