Hi Jason
I have the adapters cut but I'm struggling to get time to do some final machining and get them to the platers.
Apologies to those waiting.
The 283mm x 22mm rotors are DBA275 from a Peugeot GTi-6 1997-1999.
They're also the same as a Citreon Xantia 2.0i 1993 - 2002.
I also found a place online who sell vented variants but i can't recall the name.
