There’s no adhesive under the sills on a 430 so easy to remove. My former 355 had adhesive and was a bear to remove. My OEM sills came with the “Ferrari” inserts already in place, so sorry, but I’m not sure what thin black vinyl trim you’re referring to.
Just installed my ExoticCarGear Carbon Fiber sills. 30 min job, no issues. I used this thread for info and it’s great.
I love the carbon Door Sills. I also have the interior ones. View attachment 3189799 Image Unavailable, Please Login
