Hi. I know this has probably been done to death but I cant quite find my answer. I have an RS200 with the standard wheels (five spokes not speedlines). Like many think, the rear arches arent really filled by the wheels. I quite fancy the cup racers but as a cheaper alternative, what spacers should i be looking at? Has anyone fitted spacers but only at the rear? Did this muck about with how it drove at all? any other thoughts? cheers. Will
