A series 2 rs-four-s (factory manual) has the fork on the rear suspension, the same as the 33/34 gtr. The suspension that they got for you would be for an rs-four-v i would assume, which is automatic and they have different suspension. I'm not sure if the 260rs suspension would fit, and yes 33/34 gtr suspension with slight adjustments to the top will fit however you would need to change the rear springs as the rate would be for a coupe not a wagon. As far as i'm aware (don't quote me here though) there is no suspension available from tein for the rs-four-s, im not even sure if there is any available specifically for the 260, but im not 100% on that last part.
