Materials & Construction: Manufactured from high-grade carbon fibre with a UV-stable clear coat, this component combines lightweight construction with the distinctive weave finish that defines performance-car styling.
Fitment: This product is designed specifically for the BMW 4 Series G22 G23, model years 2020+. It integrates with the factory panel lines, mounting points, and (where applicable) electronic systems, meaning no cutting, drilling, or bodywork modification is required for a standard install. Please double-check your chassis code against the listed fitment before ordering - if you're unsure, our support team is happy to confirm compatibility for your exact vehicle.
Installation: Fitment is straightforward for an experienced installer using standard hand tools. We strongly recommend installation by a qualified bodyshop or detailer, particularly for exterior components that require panel alignment, adhesive bonding, or painted-surface preparation. Full fitment guidance is provided in the box, and our support team can help confirm the best approach for your specific car.
