Hey everyone,

i noticed a vibration in my car from about 90mph-125mph anything above that speed and there is no vibration at all.... what could cause this ?
I did a search and most indicated the driveshaft as the problem source... I doubt that this is the case here, since evey vibration is gone after 125mph.... do you think my poly tranmission mount could cause that problem ? Maybe even the Borla pipe that is almost touching something ? Weird thing is that its only from 90-125..

Thanks for your help,
Alex
