had the tracking and balancing done

and told that one of my wheels is slightly buckledÂÂÂ

but when I'm driving normal speed 30-40 mph the car is now rattling (plus had new roof) but when i do around 70-80 mph the car vibrates like mad for 5 sec then stops for 5 sec then starts again so can't be the wheel can it?

if i go faster i can just about keep my hands on the wheel its that bad

anyone got any clues to what it could be!ÂÂÂ

keep getting different answers.
the roof is rattling very bad also heard sometimes its how the roof goes back on is this true or is it just because I've changed the roof

p.s does anyone now how much a new clutch kit would cost and where to get one from
