    I've compiled a list of some of the more commonly used acronyms you might find on the site, in the context of how they're likely being used on the site. I've tried to omit the silly/less useful ones, but if there are some you can think of that I've missed, let me know and I'll add to the list.

    Maybe sn95, s197, s550, s650, also scp for super coupe performance
     
    Back when I first started reading forums I thought QFT was Quit Fucking Talking. I thought so many people were rude trolls 😆


    Maybe sn95, s197, s550, s650, also scp for super coupe performance

    I don’t know for sure but I think SN95 is Specialty-North American-project 95(ala MN12), and following that logic with later model Mustangs being global cars they were simply Specialty-197, Specialty-550, Specialty-650. That’s just an educated guess.
     
    TL,DR. PIIHB. Run like Hell.
