The problem is that the keybed is not anchored to the plate. If you look 
under most keybeds, you will see a protrusion from the plate on which the key 
bed sits. The keybed is actually screwed to it. On "Grands", and other 
cheapies, there is no protrusion. (I guess to save a buck or two.) 

If you just shim the balance rail, there is a good chance the keybed will 
continue to bow down, or, with changes in humidity, will actually bow up, 
which creates more problems. 

Several people have already offered their suggestion  of bolting a piece of 
angle iron to the back of the key bed. This will permanently solve the 
problem.
