In the images below, I show a comparison of some of the details of front and rear seats. The factory interior is on the left and the Katzkin on the right. Strangely, the two materials reacted differently to the camera flash. In reality, the wrap color of the Katzkin and the factory leather look very similar.
You may notice subtle difference in how the pieces are cut. Also, note that the factory interior has perforated leather only in the centers whereas this Katzkin pattern has perforation in the wings as well. There is also a noticeable difference in the addition of double stitching in the Katzkin which emphasizes the contrasting blue stitching color. Katzkin provides options for changing some of these construction details. As I mentioned in my last post, the most noticeable difference is that the Katzkin feels softer to the hand and puckers more in the seat wells. When sitting in them, they feel the same. I was disappointed that installation of the after-market leather did not give the car a nice new-leather smell but a more acrid new-vinyl smell. Not sure what is up with that.
