I have a 2015 Porsche 981 Cayman S 981. I bought 1) ZPR47513B Porsche Cayman S 981 (PDK without Sensors) - Front Grill Set - Black Finish, and 2) ZPR42912B Porsche Cayman/Boxster 981 (All) - Rear Grill Set Black Finish. The product material is very good and very high quality. Except for the front center grill, the two front side grills and two rear grills fit well. For the front center grill, I used 2 black screws to tie the left end and right end to the front bumper to fit better to the center opening. Overall, It was not difficult to install the grilles when I carefully followed the instructions.
