Hi Ash,

I run 2 degree caster correction on my car for a 2 inch lift. I had that exact same issue before too.
2 degree bushes suit 2"-3" lifts btw.

Get a good rubber one, it's worth doing it right the first time.
Also make sure it comes with the template so you can line up the holes correctly when pressing the bushes in.

Hope that helps

Cheers,
Martin
