I purchased these endlinks with high hopes. I used them combined with the Eibach 22mm rear swaybar, stock arms and suspension. After 3 weeks, I heard clicking on the back left of my 2015 STi. I checked under to see that the endlink was completely free and unattached form the sway bar. I found that half of the rubber on the side facing away from the endlink had completely fallen off. Upon inspecting the other side, I found that the bolt holding the endlink to the swaybar was being PULLED through the rubber to the point that it was starting to fall off, as that was occurring to the right endlink. I must mention that I was only using the car as a daily driver. Poor build quality

After going thru literally 3 front and back sets of other brand that is adjustable, I finally got the solid Kart Boys, and they're awesome. No more breaking of links which equals no more clunk clunk noises.

Built solid, you can just tell when you hold them. Wish I would have bought these first, but live and learn, or take it from me, buy these once!

Installed this on 2020 WRX along with a White Line rear sway bar. Everything lined up as it should and fitment was spot on.
