I have a question for those with variant 3's. I just picked up a set for my s14 and while installing them onto my stock rear upper mounts i found that it doesn't seem to want to bolt down all the way. When driving it sounds like the washer on the bottom of the mount is tapping it
, and when trying to tighten the bolt down the piston just seems to spin. How are you guys tightening this bolt down? I was thinking about either using an impact wrench or a spring compressor to hold the spring down while we tighten the bolt.. any insights are appreciated.
