Lets see what you get back but if needed I can call into their HQ which is only 10 miles from me. FWIW I did a small amount of work for Dymag something like 20 years ago (Finite Element analysis of carbon fibre wheels and designed a carbon fibre single sided swing arm). Their chief designer then was Mike Wilson, I think he is still there .....I sent dymag an email, ill see what they have to say.
Have you got a dial gauge that you can mount perpendicular to the discs? If you have you could quickly check the disc run out. Those calipers should generate a lot of stopping power and heat. Couple that with Chinese discs and you have a perfect recipe for warped disc(s).Spoke with previous owner and he did say that these rotors were from China. Thats a huge red flag for me
