Hiya Zep - similar with Neilc below, I also have a 4.7 2014 Granturismo Sport and looking for brakes and pads. Are there actually aftermarket ones I can use that are the same size and fit? I'm also interested in upgrading them to the big brake system some facebook members have recommended, and told to reach out to you. Could you let me know cost of this and where I can get it done? Thanks, James.
