I’d just be a little concerned that if 260 x 25mm wasn’t used in period, it would prohibit it’s use now- BUT as the Monte Carlo caliper is commonly used with small discs and 13” wheels, I guess it must be acceptable!

Well , actually Mike , the 300mm dia discs are quoted as 31.75mm thick in the Homologation .
But as the measurements are quoted as maximum,s , then I think it is allowed to machine smaller . As in the 280mm x 25mm discs being cut down to 260mm x 25mm .
