Hello Mopar enthusiast I'm hoping I can get some insight with this issue that I'm having at triple digit speeds in my 2019 Charger Scat Pack.It roughly begins around 100 mph and intensifies as it climbs up to 141.That's my top speed to date. I purchased my Scatty back in July,and just cracked 2000 miles on her this week but I had noticed this vibrating even back when she was at only 700 miles in. Now that I've gotten a little bit more comfortable with the power and speed I tend to hit Triple digits regularly and this definitely cannot be wind vibrations. I know the feeling of out of balance tires usually at double digits around 65 to 75 mph, but this feels a kinda different especially when when your heart is pounding out of your chest and your hands are clinched to the steering wheel and trembling at the same time. My neighbor has the Challenger Scat Pack and he says the only thing that he experiences is the heart pounding and hand trembling.Has anyone out there had this vibrating/(Earthquake) like experience at triple-digit speeds or is it something I have to get used to ? Any insight will be greatly appreciated.
