I have 8 sets of oval WRD shims for sale. One set is composed of:
1 x 0.1mm
1 x 0.2mm
2 x 0.5mm
1 x 0.8mm
2 x 1.0mm
From 0.5mm up it is laser cut stainless steel, 0.2 and 0.1mm is steel, laser cut as well.
They are not super precise. You would have to allow +/- 0.03mm or so. The edges might be a little rough, but because they are a bit bigger than the WRD base, I think it may not matter. The thinnest is particularly pathetic. They are elliptical (originals were not), but they fit very well, I checked on my car. The shape actually helps put them on or slide them off - easier to grab with the tips of your fingers. I think they are better, however, than anything you could do yourself without proper tooling.
I decided to have then manufactured instead of trying to make them myself. Nobody wanted to talk to me about one or two sets, I had to make 10. The thicknesses are determined also by the thickness of metal sheet the manufacturers had at hand, not necessarily what I would prefer. They made some excess number of 0.5 and 1mm, so I doubled them in the sets. They had technological problem with the thinnest ones - they could not make the stamp, laser was burning them... They could not play to much time with it, probably they made them "in their free time".
The little "shavings" you see on 0.8mm and 1.0mm picture is pieces of the backing protective foil, not metal.
It is 8 sets, I am asking EUR 20 per one poor set plus shipping.
