The ball joints should be installed with the offset--relative to the center line of the control arm--going forward. The purpose is to provide more positve caster which aids straight line stability--think of the forks on a bicycle--kicked out front, the bike is more stabile. Consider how the bike would handle if the forks were straight up and down. Non power steering cars have less caster to ease steering effort (ball joints without the offset)--but the offset type can be used for more steering "feel". -- Dave
