From 40mph upwards I can feel vibrations coming through the car's rear... It's not the tyres/wheels I've had them checked "again" today. The wheels have been balanced more times that my grans kitchen scales 40mph I can feel it starting 60mph it's more obvious 80mph+ and you can feel it getting worse the faster you go. Any ideas, I'm quite confident it's a suspension issue. I'll be booking it in this week to be checked at the stealers. Appreciate your thoughts. Cheers.
