all depends on why u wanna do it?to make money?try something new?orions bits are everywhere, and thankfully share most parts with the RST!!
dont fit disks on the back, unless u like facing the wrong way, fit some cossie 4x4 calipers and cossie 2wd disks on front, much improved!!
spax or konis as with strut braces, the back one can be hard to fit, as the seats cover the tops so getting a bar tht fits can be a pain.

interior wise, ghia stuff is the nicest with a set of recaros in front
