I ordered and installed the black CF-look paddle extenders on my OEM billet aluminium paddles, and they look great with the OEM carbon fiber strips on the dash front.
Installation couldn’t have been more simple (5 minutes or less), and they are very functional. I drive in manual mode 95% of the time, and the extenders make it much easier to shift at any steering wheel position without having to remove a hand from the wheel to reach the much shorter OEM paddles.
Highly recommended for all frequent paddle shifters!
