I want to adjust rear toe and would like to know the AF spanner size of the camber adjust bolt. A 22mm is a bit loose and a 21mm too small. Is this typical problem? Do I need an imperial size to get best fit. eg 15/16" AF?
I also notice one of the 17mm nuts is a bit rounded, can I get new ones ok?

 

Eh? This car is Japanese. Thus they would give you a weird look if you mentioned Imperial or AF sizes to them. If your 22mm is a bit loose, is it knackered? I would think a quality socket would be preferable to a spanner if possible. Rear Camber is not meant to be adjustable other than slack in the mounts so I take it you mean the two bolts that connect the strut to the hub?

Berst leave these things to the pros.

 

My Britool sockets are ok but if an Imperial AF socket is a tighter fit I will use it rather than a metric size. The error is in the AF of the jap bolts.

 

The bolts in question are at the inboard end of the rear lateral links. They are simliar to the ones used for camber adjustment and a std Subaru fitment and used for rear toe adjustment. My 22mm Britool socket is a loose fit and as I haven't seen any 21.5 mm sockets my guess is there may well be an Imperial one which is a good fit albeit not specifically the "correct size".
