Rear valance upgrade for BMW 3 Series F30 F31 2012–2018 in satin black with twin outlets

Give the back end of your 3 Series a sharper, OEM+ finish with this CT Carbon rear lower bumper trim in matte black. Precision-moulded from high-quality ABS plastic, it replaces the factory insert and introduces a clean twin outlet layout for dual tailpipe set-ups. The result is a purposeful, factory-style look without the flashy glare, perfect for daily use and enthusiast builds alike.

Designed for the 2012–2018 BMW 3 Series F30 and F31, this rear bumper insert delivers a tidy fit and a tough, weather-resistant finish that stands up to road grime, stone chips and British winters. We’ve fitted this part on customer cars and our own builds, and the feedback has been consistently excellent for fitment, durability and that subtle satin appearance.

• Satin/matte black rear lower bumper insert for a stealthy factory look
• Twin outlet design to suit dual tailpipe configurations
• Durable ABS construction for strength, impact resistance and longevity
• Direct replacement for the original lower trim with an OEM-style fit
• CT Carbon quality with precise moulding and consistent panel lines

Vehicle compatibility

BMW 3 Series F30 saloon and F31 touring, model years 2012 to 2018.

Why choose this rear bumper trim

This is the ideal rear diffuser-style upgrade if you want a refined, factory-inspired finish rather than a glossy or overly aggressive look. The ABS construction keeps weight low and resilience high, while the matte black surface integrates neatly with both standard and performance-inspired styling. It’s a smart, cost-effective way to achieve a dual tailpipe-ready rear end without compromising on fit or quality.
