Hello everyone, I just of wanted to communicate about my problems with vibration in the drive-line of my 2005 R53 during acceleration past 65 mph. I had my trusted mechanic check all the usual suspects ( shafts, joints, mounts, tire in-balance) but could not find any problem, except that the mechanic said it might be the tires. I changed the tires, very little improvement. My mechanic noticed that I had poly bushings in the control arms, I have had them for two years with no problem. He's not a big fan of poly bushings in any non-track car, as the durometer rating of the bushings are so high that vibration goes right through the joint unto other suspension components. Anyway I changed them back to stock, guess what, no vibration. So before you spend a lot of money changing components check those poly bushings first.
