Product Overview
The RC F diffuser sits low and is vulnerable to curb contact, road debris, and scratches. Owners also replace the original lower panel as part of an exterior carbon-fiber package. This component follows the USC10 RC F rear-bumper shape and uses pronounced fins to change the lower-rear appearance.
North American RC F model-year fitment begins with 2015, even though some seller titles include 2014 due to market or production-date labeling. The safest fitment range for a U.S.-market car is 2015–2019 unless the original 2014-market bumper shape is independently confirmed.
Key Features & Performance
- Rear lower diffuser for RC F USC10 body shape
- Carbon-fiber construction/appearance as listed
- Aero-inspired rear fin profile
- Low-mounted replacement/upgrade panel
- Requires careful bumper-shape and model-year verification
What Is Included
1 rear lower carbon-fiber diffuser
Fitment Notes
Dry-fit against the complete rear bumper before drilling or permanent fastening. For any vehicle identified as 2014, verify market/production date because U.S.-market RC F sales are generally 2015 model year forward.
Why Replace This Part?
Usually replaced after scraping/cracking the low rear panel or installed as part of a carbon-fiber exterior styling package.
