front caster adj?

[xspsi4]

Is there a way to get front caster adjustment since evo 8-9 are non adjustable?
I am thinking like some sort of camber/caster upper mount plate.
I don't even know if something like this exists for the ct9a chassis, Any help would be apprecieated.

I know Perrin makes a PSRS or Caster kit. They claim up to 1.5 degrees over stock
