I think I've stuffed up I ordered a 203 rotor for the front of my 2017 sight it currently has a 180 rotor with a bracket. So i ordered a 180 to 203 bracket instead of a 160 to 203 bracket. My question is can I stack the new bracket on top of the old one or should I just order the right one. Cheers

Get the right one. As well as spacing the caliper off the fork, the different adaptors change the tilt of the caliper against the fork - as it is with a 160-180 adaptor you need curved washers under the bolt heads to correct for the caliper tilt off the posts. Double-stacking the adaptors will almost certainly change the caliper angle too much for the bolts to go in square, plus you'll need bloody long bolts, which will suffer a lot of stress and eventually break - if they even go in.....
