I've got a 2021 GT with PP1....called Covercraft and they told me the bra that they have available will not fit the PP1...probably due the splitter. They told me they have nothing currently in the works to make one that fits. I was contemplating maybe removing the PP1 splitter from my car and get a splitter that is on a regular GT....or....I'm thinking the GT350 bra may fit with a bit of work. In your opinion, looking at the fit of your bra on your car, do you think it would fit on a regular GT with the PP1? Thanks!Funny!!! You can thank me for that Colgan GT350 bra! I pleaded and negotiated with them for eight months during 2019 and 2020 to get them to make a bra for my 2019 GT350! After some meaningful and productive discussions with the President of CoverCraft Industries, (they own Colgan), he agreed to have his people design one. A very nice, understanding, and patient individual LOL! It's not an easy or inexpensive process for them to design a bra, so I was extremely pleased with their decision to design one for a limited production or customer requested GT350. I received the first one last year and it fits perfectly. I've used Colgan Bras for my past 3 GT500's since 2007 and some of our BMW's. I've found them to be of excellent quality and they definitely protect the vulnerable front end paint. I only use it for long trips and it does the job of keeping the front clip free of rock chips, bugs, and all other material that shows up on our interstates! Colgans do fit tight which is a good thing at highway speeds and they are the best bra available. Hope you enjoy yours! So glad you ordered one! At least they've sold two!!
