The 2wd cosworth coilovers will fit the standard hubs. The problem is that the standard hubs give less room for wheels than the cosworth hubs do. On a standard Sierra (with normal hubs) even the standard cosworth wheels don't fit without spacers. They rub the shock, not at the spring platform, but at the side of the shock tube. So it doens't really matter if it's a standard shock or a coilover, as the tube is just as thick. Of course the cosworth wheels fit without problems on cosworth hubs.
