Rear Wheel Alignment FRV

[ChrisTopper]

Hi, my vehicle is suffering rear inner edge tyre wear. I am aware there is some adjustment that can be made on the lower arms, my question is - is there any adjustment that can be made to rear wheel alignment. I believe that the 'adjustment ' nut impacts on the rear camber and is adjustable for each wheel. 

Anyone can provide some more information on the subject or point me in the right direction ?

My vehicle has clocked up 145k miles and has always been a bit heavy on rear tyres, even after 4 wheel alignment at a reputable garage chain, in fact on that occasion an adjustment was made but insufficient adjustment to be within tolerance. The cars history is known and no accident damage that could account for my problem. BTW the car drives fine and handles well in any weather, its just I fancy having a go at getting it to be more gentle on tyres.

Thanks Chris.
