I have a lower rear control arm bushing that's showing signs of needing replaced, so I figure now is a good time to just replace all my control arms. My Dad put Rusty's adjustable rear uppers on his '06 Rubi, and they looked good to me. I'm thinking I'd like to stay with clevite bushings. What's wrong with Rusty's arms? Most things I read about them are negative. FWIW I'm running 2" BDS springs, and don't intend on going any higher.
