the best thing to do is speak with an rta or whatever similar association in the act accredited engineer talk to them tell them what your planning to do and what would be required for them to certify them (yes more than likley you will need it to be engineered)
Make sure you talk it though with the engineer before starting the project so that you dont have to waste time/money fixing things up to make them acceptable. Some engineers will talk things through for free some wont
it looks like an awesome brake upgrade
