I going to upgrade my swaybar bushing. But which one do i need. The non-greaseable type or the greaseable. And does it make any differents

 

I'd go with non-greasable because that's one less part that will fail or have the opportunity to fail when you least want it to. I run regular poly-bushings on my ST swaybar and they work great. I also removed the top poly busing in the rear endlink to increase preload. I love the way my car handles like this and don't plan on doing anything to it other than maybe getting some higher spring rates.
