Now you showed two different types of bushings… One Poly-Urethane the other Aluminum. What are the main differences between the two? ---

The collers are meant to be used with stock bushings. The polly urithain are meant to replace your stock busing and can not be used with the collars ---

Actually, the polyurethane (assuming that’s what it is) in the middle pic looks to be more a spacer/collar than a bushing. I wouldn’t trust a plastic to resist the forces it would encounter as a subframe bushing. The top pic looks like aluminum (or stainless) and those are collars. The smaller ones would go on the bottom, and the gapped ones on the top (I don’t know why they’re gapped though.) The bottom pic is just a collection of straight-up bushings, almost certainly aluminum. ---

The smaller ones would go on the bottom, and the gapped ones on the top (I don’t know why they’re gapped though.) They are gapped so you dont have to drop your whole subframe to install them only losen the 4 bolts holding it up and slip them in. ---
