I also agree princess calipers can be a great little setup I have them on mine and they work great and I'm using green stuff. I'm sure I'm using cosworth disc tho my mate made the setup for me with all the spacers needed that's what he had on his 350 bhp mk2 cortina and that's what's on my chevy capri a very good setup indeed he swapped to a Porsche setup and hated it compared to the princess option so swapped it back till I think he ended up with Aston Martin brakes in the end but he's an engineer and can make anything fit and work he's so handy to no. Lol.
