IE rear subframe bushing install question

[DoneRightBimmer]

Quick question about Ireland Engineering rear poly sub-frame bushings going to install today. I need to know if when installing the bushings do you reuse the large washer that goes in between the body and original bushings or are they designed to work without the washer?

Thanks for help

I don't think this is IE specific, but use the washer.....

I dont use it when installing hard delrin bushes but you should probably check with ie to be sure.

always reuse the washer, does not matter if its factory, poly, delrin etc.
