BMW 3 Series G20 | Prepreg Dry Carbon Fiber Vented Front Fenders

BMW 3 Series G20 Prepreg Dry Carbon Fiber Vented Front Fenders

Engineered for BMW 3 Series G20 owners, this Prepreg Dry Carbon Fiber Vented Front Fender set (left + right) delivers motorsport-inspired aggressive styling while providing functional vents that release hot air and pressure from the wheel well. Made to factory-spec tolerances by leading manufacturers around the world and quality-controlled by BYC Performance, this BMW G20 carbon fender set bolts directly to OEM mounting points with no cutting or modification required.

The integrated vents reduce aerodynamic drag and aid brake cooling by relieving pressure buildup behind the front wheels. Compatible with every G20 engine, from the B48 in the 320i and 330i to the B58 inline-six in the M340i, this set is the ideal visual and functional upgrade for drivers who want to complete the BMW M Performance look.

Key Features

• Left + Right Set: Shipped as a matched pair; replaces the factory fender panels.
• Functional Vents: Release hot air and pressure from the wheel well to reduce drag and aid brake cooling.
• Prepreg (Dry) Carbon Technology: Cured in an autoclave under high heat and pressure; homogeneous resin distribution, a more consistent weave.
• Lightweight: Significantly lighter than the factory steel/plastic fender; reduces unsprung weight.
• 2x2 Twill Carbon Weave: Authentic carbon pattern under high-gloss UV-protective clear coat.
• OEM Mounting Points: Plug & play installation on factory bolt and clip locations.
• Signal/Sensor Compatible: OEM side marker light cutouts preserved.

Prepreg (Dry) Carbon vs. Wet Carbon: Which Is Better?

Most aftermarket carbon parts use wet lay-up: resin applied by hand and cured at room temperature, leaving 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 G20 carbon vented fenders requires removing OEM fender panels. Professional installation is strongly recommended:

1. Remove front bumper, headlight and front wheel.
2. Detach the inner fender liner.
3. Remove the original fender bolts and pull the OEM panel.
4. Transfer the side marker light to the new carbon fender.
5. Align the carbon fender and secure with factory hardware to the manufacturer's recommended torque.
6. Check panel gaps and align with adjacent body panels.

Care & Maintenance

Wash with pH-neutral car shampoo. Apply carbon-safe sealant every 6 months. Keep pressure washer nozzle at least 30 cm from surface. Clean dust and debris from vent channels with a soft brush.

FAQ

Does this fit the G20 LCI (2023+)?
No. The G20 LCI uses different front fender and headlight geometry; LCI owners should contact BYC for vented-fender availability.

Are the vents functional or purely cosmetic?
Functional. They release hot air and pressure from the wheel well, reducing drag and aiding brake cooling.

Compatible with 320i, 330i and M340i?
Yes. Fits all G20 Sedan gasoline and diesel engine variants: fender geometry is engine-independent.

Is this the same as the BMW M3 G80?
No. The M3 G80 has wider fender flares; this set is designed for the standard G20 body only.

Will it fit without the M Sport bumper?
Yes. The fender panel is compatible with all trim packages (Luxury Line, Sport Line, M Sport).
