My 02 WRX is vibrating at 90mph just like a wheel out of balance it is gone by 95ish but it is doing my head in, all wheels have been balanced and still its there, to be fair I noticed it when I had my front discs and all the pads changed but if it was a disc surely it would shake under braking? otherwise WTF is it? any ideas?

 

was the hub clean when the new discs were fitted? only needs a bit of crap between disc and hub face and the wheel wont run true.

 

Well I am assuming these people at the garage know what they are doing however I may take them off and have a lookie if they are ok what next? I am really getting pissed off with it, to the point where if I dont cure it soon the cars going, I just dont enjoy driving it at the moment.
