I would start by getting your rear wheels balanced. That is the easiest and cheapest.

balanced back tyres and front no luck still vibrating.... :zx11: anyone else with any ideas....
actually i was thinking of chaning the back wheels and putting different ones on ... would that help?

I would check the rear axle bushes and the rear wheel bearings. Also while you have the wheels off, check the brake pads and the brake discs !

when i went to get the the wheels balanced the guy there said that i had a space between the wheel and the bak and that i need spacer between them... could that be the problem!! just had mot done and everything was A ok. but will chek them myself. thanx

Make sure the tyres are OK, no damage to sidewall etc.

As mentioned check wheel bearings.

You have not kerbed the car recently or taken a large pot hole?
