This is a brand new & unused set of 4 x stainless steel spigot / hubcentric rings which enable you to safely fit 4x100 BMW, VW, Audi etc wheels with a 57.1mm centre bore to 4x100 Honda, Rover & (classic) Mini cars, which have a 56.1mm centre bore. (Apparently some Subarus as well but I don't know anything about Subaru fitment)
They are quite hard to find in this size (at least they were when I bought them) as the reduction in centre bore is only 1mm so the rings are only 0.5mm thick.
I bought them from a well renowned UK seller who manufactures them himself & has a very good reputation with 1000's of satisfied customers over the years. I just searched for him on ebay & he's stopped production now & is only selling his remaining stock so these are well worth picking up now while you can.
More reasurring than having plastic rings, & being stainless they are highly reisitant to corrosion. I can testify to their quality, because I used some in a different size on my car & have just removed them after 2.5 years. They still look as good as new with ZERO corrosion. If you want to see photos of mine after 2.5 years use please ask.
