Introducing the R1 Rear Bumper: Precision in Prepreg Carbon Fiber

Our R1 rear bumper is expertly crafted using prepreg carbon fiber, combining cutting-edge lightweight technology with striking aesthetics. Explore our range of options designed to cater to your unique needs:

1. Dry Carbon Rear Valance Kit

Engineered for maximum weight savings, the full carbon exposed rear bumper is a top-tier option for those who demand high performance and aesthetics.

Fitting Guidelines

• For 2008–early 2011 CBA models: Upgrading to a later DBA/EBA diffuser is recommended for optimal fitment. Alternatively, our LB-style diffuser offers a refined look for the center section.
• For 2012–2016 DBA and MY17 (2017–2023) models: These models are equipped with factory rear undertrays, so no additional modifications are required.
