yeap i eventualy found out what it was thanks to whitegze/ matt for helping me look for the problem but we had little luck with the problems i originaly thought..
following your checklist magnew..
Does your steering wheel shake at those speeds, if so could mean the alignment needs rectifying. [NOPE - got wheel alignment month and half ago]
If its a grinding noise its most likely worn wheel bearings. [Hmm me and matt checked for that.. Nope]
If its a clunking noise it could be loose bolts in your suspension. Check all the strut tower bolts. The shock nut for play.[THIS COULD BE IT.. ALL SHOCKS EXCEPT FOR THE BACK RIGHT REAR.. THIS IS THE ONE MAKING NOISE.. I LIFTED THE CAR UP AND SHOOK THE WHEEL.. IT WAS MAKING THE NOISE I HEAR FROM DRIVING.. REAR SHOCKS HAVE CRAPPED OVER TIME TO GET REPLACED)
Check your camber pins and make sure they are in a suitable camber. If its too positive or negative it will make tyre noise. (ALSO COULD BE NOTHER THING)
Check for tie rod free play and other vital suspension connections. The bushes could be perished. (PROBABLY TOO)
opps sorry for the caps but yeah atleast i know where to look now! suspension i had a feeling it was that all along
