Vibration and resonance in cabin 35-45 mph

Have a horrible vibration around 35-40mph, doesn't change with rpm or road conditions. Thinking it's either driveshaft related or maybe U- Joint? Any ideas?
Car goes into service in 2 days

No idea. Does it sound like it's coming from the drivetrain or the body? Have you modded the car at all or recently changed anything? Maybe bad motor mounts? Unlikely for such a new car.
Warped rotors? Wheels out of balance?

Let us know what the dealer says.

Sounds like driveshaft possibly. Car has m performance exhaust and m performance coil overs but otherwise stock
