If it helps anyone I purchased a set of four well three usable black diamond cut wheels with centers when at the Oulton Park round of the BSB and was stuck trying to get an extra one to complete a set, I have a few standard silver 197 rims so I brought a couple to my local alloy wheel guy in Cookstown (MJE wheels) anyway it works out you can diamond cut the standard alloys to match, so I hope this helps some being held to ransom looking for a replacement diamond wheel.
