Just had a 2inch (50mm) suspension kit fitted, I understand that I should not need a caster correction bushes fitted on my Patrol 2005 3l, had a wheel alignment and showed castor why out, not sure what all this means but the final measurement is +0 26' +044' so do I need a Castor Correction, Before my upgrade to a 2 inch, afew months ago the caster final was +4 21' +4 42' any help thanks Hutchsky
