Hello, I just got an ATS 3.6 Black and caramel, beautiful car ($50K). Premium, with magnetic ride, 18" forged Aluminum wheels, run flat tires (worst tires I have ever had). I'm very disappointed with the ride. Switched my M3 for this CADI, and I am already regretting it, but there is no way back. So I have to make this car enjoyable. I'm thinking on putting Eagle 1 Goodyear or Michelin Pilot. I believe it will change the ride dramatically. Although, Cadillac is not payment for it, it will come out of my pocket. I will really appreciate your thoughts. Comments on cool air intake and exhaust (low noise), are appreciated. Good luck guys.
