I actually ran into an issue today on assembly prep. I have 3 sets of bumpstops:
It looks like the ones on the far left are for the front, but of the 2 sets on the right, I don't know which ones are for the rear. 1 pair came with my 2011 STi springs. The other pair came with my 09 WRX tophats.
Neither pair is large enough to go over the piston on the rear Konis, while the pair on the left fits on the fronts without an issue.
First, I don't even know for sure that the Konis require the re-use of the bumpstops, but without them in place, the dustboots seem to be just hanging out on the pistons.
Can anyone shed light on the proper bumpstops, any trimming that is required, and whether I need to drill out the center hole to make them fit over the piston in the rear?
My usual WRX suspension helper/go-to guy has Bilsteins (which have integrated bumpstops) so he was not helpful.
I am just about ready to assemble these things but I wanted to be clear on the dustboots/bumpstops before I go forward.
Also, Koni ships the struts/inserts with plastic discs. Are they to protect the pistons and the top of the inserts/struts during assembly, or do they stay in place permanently?
