Would these Cars Benefit from more Caster?


Recommended Posts

My front LCA bushings are probably due for a replacement, if I'm gonna spend money on new ones, thinking of just getting a caster set (since the non-caster AVO ones are same price).

 

FSM says Outbacks have 5* of caster while Legacy's have 5.91-6*.

More caster the better right :)? When I was first creating this thread, I figured PS pump might not appreciate more caster, but seeing that Legacy's have 6* I think there should be no issues going 5.5*.

Did a dynamic camber gain graph for the 2012 Outback.

I think the obvious answer is yes increasing the caster by even 0.50* will make a pretty good increase in camber gain.

Just note that more caster is more load on the power steering pump. I really recommend a PS fluid cooler if increasing caster.

Very true, though it would only add 0.50* totaling 5.58*, 2.5i Legacy's have 5.91* of caster. I don't think 2.5i Outbacks have different power steering pumps then 2.5i Legacy's so should be no problem either way.

Can you share a link to a power steering cooler kit?

 

With Whiteline top hats and LCA bushings, I have 6.7* of caster.
