After the post that have been on here, and the useful thread someone gave me to the RSOC website on the issue, i pretty much figured my problem was with the wheels. Took it to the local alloy wheel place and it turns out i had a spacer missing from one of my alloys.

this guy wanted a £10 PLUS the £20 i had just paid for 4 bits of fuckin plastic, so i told him to stuff it and took it to the local garage where my mates work. Basically turns out that the other 3 wheels DID have spacers, and my mate recons the guy probably pulled a fast one andslid it out on the sly. So instead, i took all the old spacers out and put all the new ones in. Turns out the steering wheel shake has more or less dissapeared. Still slighly on braking but it probably pads.

Had my first 85 mph experiece last night, with no shake, on a 40 road. I talked the copper out of the dangerous driving charge. 3 points and a £60 fine for a 60 in a 40 (he said i was doing 85!)
