The inserts were always steel, the shims are also steel. Only thing you need is pads, calipers, 13" cobra rotors, and lines
Lowranger96, how are you making out with the kits?
Do the pads need to be trimmed with your kit?
That’s a plus as I’d rather not trim anything, question in regards to the spacer or not using it, any machine shop with a mill should be able to shave the calipers fairly easily, I already run a spacer and need all the thread engagement possible.
