I'm surprised nobody seems familiar with AP Racing's own Competition Kit (not to be confused with their strap-drive BBK, which is more geared towards road and occasional track use). Their competition kit features full bobbin-float 368mm x 36mm - 72 vane front discs, and 352mm x 26mm - 48 vane rear discs. The calipers are similar to the ones in the Essex kit in that they are meant for the race track, i.e. S.S. pistons, knockback springs, no dust boots, and unpainted.
Below are links to AP Racing's description of the kit.
