Hi, looking for some help here guys. I have an RS 133 which l know is not a cup version per se but l need to find out whether it has the cup chassis. My reason for asking is l got an advisory on the MOT for rear shocks and l need to know which ones l need (also, do l work over on Saturday morning to pay for them or sell the house?) My car has 17" wheels as per the cup upgrade but l don't know whether they were just added for aesthetic reasons or came with the cup chassis package. Any ideas how l can tell?
