Kilmartin sells shock mount plates that allows you to adjust camber but the=
y can also sells you a set up for 4 degrees of castor.

Soooooo ... that could be the cause of hard turning?

Bear in mind that sagged rear springs can add to that.
2 1/2 degrees is way too much.

Bob,
I think you mean camber angle.  Caster is the forward/rearward angle inclin=

Not sure what the factory camber angle is, but what you stated is probably =
close.

Listers,

What's the recommended setting (my version of the shop manual doesn't
specify one)? I think the BJ8 manual recommends 1-2deg pos.
