Yes that is caster. We use multilink rear suspension to my knowledge and the lower you go on that the further the arm moves on it's axis (there is one trailing arm that is connected to the body or frame of the car). I'm not sure though if that could ever be adjusted. I think you would need a whole slew of arms just to get the wheels in the center of the wheelwell again along with upper mounts with spherical bearings. It would look cool though because all the arms that you see under the car would be shiny and new! Haha.
lol. thats true. have you looked at the Megan Racing rear control arms for the 90-97 accord? they look like they would bolt right up to our chassis.
i looked at the rear suspension for the 1st time the other day and i was like "shnit thats a lot of arms..." lol. but immediately thought of these from MR. they look like they would fit. idk.
