So from everything I've ever heard/read/seen LCA's with at least one end running a bearing vs a bushing is the way to go for performance. So, based on that and their fantastic reputation I'm planning on a set of Team-Z lower arms for the rear of my car. And since I'm gonna be in there I'd like to freshen up the upper arms as well. I was thinking a set of new rubber or urethane bushings on the body side and run a set of spherical "bushings" in the axle end from Team Z or SKRC. I don't see much mention on the internet of them and if they justify the cost. And yes I know that they'll be harsher and noisier, my car is already "not a street car' by some folks' standards so I'm not really concerned with anything other than making it perform better at this point.
