My GT Premium, Vert, PP, AE, manual which is 2 weeks old tomorrow has an issue with the windshield shuttering, vibrating or rattling at 79mph to the point I immediately slow down. Ford has been responsive but I need the dealer to diagnose the issue.
I am wondering if this is a common issue and...
Anyone else here and feel the loud vibration with the top down and traveling 76-79 mph? I believe it is the rubber strip across the windshield acting as a seal when top is down. You can definitely hear it and feel it,
Looking for objective information on actual HSP and Torque gains with installing headers. There seems to be subjective information floating around but I would like to know from members with stock motor and long tube headers what the actual Dyno Tested gains are.
Thanks and appreciate your feedback.
