I really enjoy my 17 GT PP1 Auto convert. I added GT350 gauges and trim KYB adjustables W/ Ford racing springs,BMR 35mm front and rear sway bars, Ford Borla exhaust and GT 350 parts Next is the Power pack 2 and a Steeda X pipe
Did the BMR front brace KYBs Adjustable Yellow shocks W/ Ford Racing springs all around and BMR front and rear sway bars.Also did the Jacking rails. Also installing the Steeda X pipe next.
Penn Fed is also a very reasonable option It costs $5 to join and they give you $250 cash if you re finance your new car. I have done 2 deals with them and no problem good luck
