I bought original bolts when i replaced rear disc afew months ago, then saw some S/S on ebay @ £10 for 8.. great price, last week put my spare wheel on minus disc, so thought use the new bolts... I think they're made from a new material.............stainless putty!!!!!!!!!!. They maybe cheap but are not worth it. Can't comment on the bolts from Wemoto @ £4 each. Just a word of caution.
