If you have a RS Four V then the mount on the hubs are different. If you have a RS260 then they will fit. For the RS Four V, 33gtst rear shocks will fit perfect, so any variant of coil over for 33 gtst will suit. For the front you need 32 GTR shocks, so any variant of coil over there will be fine. If you look around on ebay and the like you can sometimes pick up stagea specific ones. The E-bay japan is one of the best. Only problem is you will usually need to know someone in japan to have them sent to them, and then get them to forward tham onto you.
