Stock was 475 with 5 mm preload, I think there were 4 preload slots, so you'd need a preload washer of some sort to make 460 work or you would end up with zero preload on the lowest preload ring. You'd better look at the manual for preload rings, I'm at work next two days so can't have a look. The kyb springs were 470 that Steve sent.
