I don't think this is normal, the top of the rear wheels/tyres lean-in towards the centre of the car, only very slightly.

What normally causes this? Wheel alignment or bent axle or ???

If it's just slightly leaning, it's normal. Wheel angles in 300-series are that way.

Its fine, it should have a tiny bit of negative camber anyway but the dedion setup does sag a little with age making it slightly more pronounced. Nothing to worry about.

Thanks so much guys, I thought there must be something seriously worng under there. Phew

Jim's one does that too, but it is also chewing the insides of the rear tyres, so I think the camber is a little too much......

Sound like it is leaning in a bit too much, perhaps time for a trip to wheel alignment joint eh?

Cheers!

Afaik, if rear tires are leaning too much it means that one have to start looking new rear axle
