I also believe the fiesta is a good chassis for a tracka car despite the short comings. I'm duking it out on track with 60-100+k cars. Panozs, Gt350rs, 911s, Caymans, M3s, C6/7/8 vettes, etc. All while on 205 or 225 v730s. I do make 380hp though so that helps but these cars can be made pretty fast for way less money than the big boys. My setup FBO 2860 e50 XDI HPFP and injectors, swift springs b6 shocks(soon to be FA510s), 15x8 +35 wheels, Mfactory LSD, -2.5F -2R camber, Autopower roll bar, Reyland/APracing Front brakes and svt rotors/brackets rear, Hotchkis RSB, TB 4pt brace Verus canards, MGC hatch mounted wing, 30-32psi FandR Hot on the v730s. Federal rsrrs I ran 33-34psi hot. So tire pressure should be lower than the door says while hot.
