Hey all, my car has recently developed a vibration when I'm in 5th or 6th cgear and slowly climbing between 60-80mph, recently I have fitting 330mm ksports and also new wheels with second hand tyres (my tyre shop said they wheela are fine and have balanced them twice) there is no vibration on the brake pedal which means it cannot be disk. When I'm I'm a low gear with foot to the floor it does not happen even if I leave it at 70mph.
Any suggestions what would be the issue?
