i have a problem like this the steering goes really light and vague and the brakes tend to pull from one side then the other i think mine is Geometry as i have new discs and pads and new shocks and springs. i put new wishbones on and its made ie worse as i think the wishbones are moving on the bolts but the bolts are dead tight. im going to fit poly bushes to my old wishbones to see if that cures anything hopefully by Billing
