Shiming out slop

Hey Guys,

My hyper st is very sloppy...

Trying to rectify this as its beginning to get unpredictable and i'm starting to break alot of arms...

Getting kinda expensive so i need to try and sort out the problems...

i'm gonna replace all the pivot blocks, hinge pins, arms and hubs in an attempt to remove most of the slop... but to remove the rest of it... what can i use to shim it?

Thanks guys, awaiting answers
