CarBahn Trunk Liner by WeatherTech | BMW G8X M3/M4 Competition Models

CarBahn Cargo Protection System Your M3 or M4 isn’t just transportation—it’s an investment. The CarBahn Cargo Protection System is designed to keep it that way, delivering OEM-grade fitment and real-world durability for daily use, track days, and everything in between. Digitally modeled for the BMW G80, G82 G83 chassis, this cargo liner provides full-coverage protection for the trunk area, with raised perimeter edges that help contain spills, dirt, and debris before they reach factory carpeting. Whether you’re hauling gear, groceries, or weekend project supplies, your interior stays protected and easy to maintain. Engineered for Real Use Constructed from a custom-blended thermoplastic elastomer (TPE), the liner is built to handle abuse without cracking, curling, or stiffening—regardless of temperature. The textured surface helps keep cargo in place under acceleration, braking, and cornering, making it ideal for performance-oriented drivers who actually use their cars.
