Has anyone had the different pkgs from FRPP installed on their S197? If so, what were they and in your opinion on whether or not they did what you expected, were they worth the money and where did you have the pkgs. installed? For example I read on one forum one member looking to convert his car into a Shelby GT using the FRPP catalog. What I'm trying to find out is if FRPP is worthy of my Stang or are the more focused aftermarket companies making better products and are the ones to purchase.
