So I don’t surprise you all. I have 4 sets left and will ship them in the UK for £400 for a pair all in. These cost me £450 per pair to make. These were not anodised, but cerakoted, so a hard wearing surface too. Feel free to check out getting a CNC firm to make these from billet 7075 Aluminium and you will find out that this is a good price.
Hopefully this might shed a little light on the various minimum thicknesses Brembo quotes for its cast iron discs: Further to @Jon916 the OP's enquiry, I dug out a set of early cast iron floaters I bought years ago and had kept, 'in stock' for any one of my numerous projects. Now that I'm in project disposal mode, I offered @Jon916 the discs and then we came to the Min Thickness question... nothing stamped anywhere on the carrier, but I measured them to be 4.66 & 4.76 . However we could not find anything definitive for these discs so @Jon916 asked the forum for pointers on a separate thread and @Chris came up with the answer - check the edge... and there it was! (see below) However, in trying to find the answer I spent a sad few hours trawling lots of Ducati forums past, present and foreign and skulked around Brembo web entries. I think it was one of the Brembo pages where I read that before they decided to abandon cast iron altogether for motorcycle brakes, they made changes to the cast iron they were using. This all came about after a few discs cracked, both at race tracks and one, or two, in road use. Their idea was to make the casting less brittle. As can be seen from the edge pic of my discs, the Min Th for earlier discs seems to be 4.5 yet @Android853sp later discs are 4.00, no doubt the later material and the booklet pushing that figure to 3.5 probably reflects the increased confidence in the properties of the later cast iron offering before Brembo dumped it all together.
I have a suspicion that your discs may have been racing discs which tend to be thicker. The race discs I have on the V4 are 6mm thick as are the 748RS discs. Andy
