I love all of my MADNESS products in both of our Jaguars. Also, I wanted to tell you, I have the new facelift (2021) F-Type R & the Carbon fender trim fit perfectly. All of our E-Pace interior carbon trims fit like a glove and we're proud to purchase from an American company.
Thank you MADNESS, we appreciate the terrific products!
The carbon fiber side skirts look great on my F type. The quality is great the carbon weave looked perfect and I am very please. They are comparable to other manufacturers but the curved design is spectacular.
