Vibration at certain speeds
Hey guys, my 07 coupe manual has a vibration that occurs at 60km/h and then disappears but at about 90km/h it comes back with a vengeance and doesnt go away and just gets worse the faster you go. Nothing is shaking but a pretty solid vibration that is hard to ignore. It's got fairly new Pirelli P zeros and i've had the wheels balanced at Bob jane. I took it back after that didnt fix it and they they thought it was hub spacers/rings missing but that didnt fix it either. Anyone had anything similar? I'm guessing its driveshaft related as it feels like the rears are where the problem is. Any help or a place to take it to that knows what they are doing in Brissy area. Cheers guys
