Shudder at speed

[Solitude]

Looking at the back of the car, it appears i have a slight camber (negative i think as top of wheel leans in) on both sides.
Driver side is slight, but passengers is more pronounced.
Car is quite twitchy at any speed, but get up to 40+ and steering starts to shake, but it feels like it MAY be coming from the rear.
Do you guys think the two are linked ???
TIA

I would jack the car up and check the play in the wheel bearings, it is quite possible to two are linked - the usual causes are quite simple ranging from wheel balance, wheel bearing to bushes.

The rear should have 1 to 1.5 deg. of negative camber. When did you last have a geo set-up? You could have worn ball joints, steering uj's, front wheel bearings, track-rod ends etc., but all of that should be picked up at MOT time. Dinged wheel is another possibility.
