i bought a new set ofcp 5200 calipers to go on the back of my car

there are for 32 mm discs according to ap website which is correct and what i ordered

problem is they will only take a 28mm disc

with the new pads in the 32 mm disc wont fit

the groove inside the caliper is only 35mm wide so even if i ground the pads down there would only be 1.5 mm per side before it would catch and they are floating discs so i dont think this will work

any help would be great
