I'll have to disagree, you really don't need all those fancy parts. With some polyurethane bushing all around, on all of the arms, and a good alignment is all you need. Chamber doesn't wear out the tires much, mostly it is the toe that you get from lowering and not doing an alignment afterwards. Up to 2.5 degrees of negative chamber is actually still considered good. With "proper" parts you won't need all that crap because a car that is too low (one needing the extra adjustment) is the one with improper suspension geometry and will actually handle worse because it won't have enough suspension travel.
My
on this.
