The shims would go behind the brake dust shield or before it, but it would use the same attachment. I have yet to tear into it also but from the diagnostic look on the FSM, it looks like there is a bolt that holds that shield on and and I would use that same bolt to hold the shim from moving.
Only one problem with this, most of the b14's have 1/4" toe in, but it also very's per car. Like I know my toe is messed up in the back for some reason and I duno why, its off and shouldn't be because the only way to change the toe is by that beam bending. So I was gonna see if I could look through all the universal ones to see how close they were to fitting, and I also had a idea to have my brother CNC toe plates up just for the 1/4" toe in.
