When accelerating in these higher gears from 1600 to 2100rpm there is vibration and rumbling sound, I think from the back. It stops around 2100rpm while accelerating. If I put the car in sport mode or just put the pedal to the floor, then the car runs perfect, no problems at all. I bought a guibo and center bearing and my mechanic is going to investigate. My car is tuned and has 90.000 miles on it. There is no codes and engine/gearbox runs perfect. Hope some of you have some advice where to investigate. It must be something to do with the speed of the driveshaft and torque applied maybe differential?

Try to check your differential bushing, part itself cost almost 1500 USD without labour, got the same problem with my 550gt drove before, the differential bushing is losing that why u can obviously feel like the car had vibration when u are accelerating, change it immediately
