Hi everyone does anyone know where i can get shims to sort the really bad camber on the back of sierra back arms. As you can see from the pics one side of the tyre doesnt even touch the ground.

 

I ran 3 1/2 degrees on one of my sierra's and it made no discernable difference to tyre wear.
Mike R shims simply go behind the hub to adjust the TOE, but you could always put them in the top two holes to de camber a bit instead, but they are so thin that they won't achieve a lot.
What about taking some measurements and having the hub faces machined ?
