BMW M3 G80 / M4 G82 Prepreg Dry Carbon Fiber V Spoiler

Engineered for BMW M3 G80 and M4 G82 owners, this Prepreg Dry Carbon Fiber V Spoiler mounts an aggressive V-shaped splitter at the center of the front bumper for unmistakable track-inspired presence. Manufactured in Europe and quality-controlled by BYC Performance, this BMW G80 / G82 carbon V splitter bonds directly to the OEM lower bumper surface.

If you're building a serious BMW M3 G80 tuning or M4 G82 modification project and need a head-turning front-end accent with real downforce, this dry carbon V spoiler is built for you. Autoclave-cured prepreg carbon is highly resistant to road impact and high-speed airflow stress. Fits all S58-powered current-generation cars — M3 G80 Sedan, M3 Touring G81, M4 G82 Coupé and M4 G83 Convertible (473-543 hp) — across every trim, including Competition, CS and CSL.

• High Strength: Carbon fiber offers very high strength for its weight.

• UV & Chemical Protection: Long-life clear coat protects against fading, cracking, and road debris.

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

V spoiler installation uses 3M VHB tape with mechanical fasteners. Professional installation recommended:

1. Raise the vehicle and clean the lower-bumper surface with isopropyl alcohol.
2. Test-fit the V spoiler and mark its position.
3. Peel the 3M VHB backing and press firmly.
4. Torque the supplied screws to the manufacturer's recommended torque.
5. Do not wash the vehicle for 24 hours.

Care & Maintenance

Wash with pH-neutral car shampoo. Apply carbon-safe sealant every 6 months. Be careful with parking curbs — the V spoiler's low stance can scrape.
