I'm sure you're all tired of bushings threads, but i have a very specific question which has proven difficult to search for.

Obviously it's cheap and easy to get a polyurethane master bushing kit, but from what I understand some of the joints on the rear trailing arm articulate on two planes rather than one. It would seem that urethane is the wrong material for such a joint, and the bushing should be replaced with either rubber or a heim joint. Seeing as my car is still a street car, i plan on getting a rubber bushing.

Which bushings in the suspension should remain rubber? Should bushings be changed simultaneously with the springs and shocks to prevent damaging any components?

Do you mean the DTSS bushing? Unfortunately Mazda wont sell it.. It's a specific rubber and has a very specific cut out and positioning that we mere mortals could never replicate :/

Looks like it's NLA from Mazdatrix.. [It was the whole knuckle or hub, whichever one it's pressed into]

Otherwise I haven't heard of any other bushings that should remain rubber when everything else is going poly

That may have been one of them. I was on the fence about eliminating the DTSS anyway. I feel like that's not the only one, though.

I know the 1st gen guys recommend poly up front and rubber in the rear, but i was trying to figure out which ones specifically should be rubber
