The car came fitted with Alcon Monobloc 4 Pot calipers with single piece 345mm EBC discs. The discs are somewhat past their sell by date, as can be seen from the picture! Badly lipped and the grooves have been completely worn away.
Original One Piece 345mm Disc with Alcon Caliper
I decided that since the discs need replacing and that to fit the 345mm single piece discs the original brackets had been turned upside down and spaced out with washers (which I felt was not be ideal for track use left alone road use!) something different is called for.
So instead of using the Alcon 343mm discs and bells I will switch to a 356mm disc and alloy bell set up which would need a new single piece calliper mounting bracket. So to have the calliper mounting brackets machined, a piece of T6082 material is required:
T6082 Aluminium
Once the calliper was mocked up onto the new discs using the original brackets and some spacers to allow accurate calculation of dimensions:
