help from latin america

hi my friends, im writing you from santiago chile, if my english is not good at all please sorry.
im actually have a 406 coupe 2001 3.0 V6 AUT with brembo brakes, the problem is that, i want to change the wheels. i already bought a momo corse 17x7,5 wheels with 225/45/17 tyres.
my question is the following:
the wheel need a very open offset, and the brembo pad is very big, so i need to put something that here we know as spacer, to join the wheel to the brake base. i need to know if it is safe.
or if someone who have that model and already have 17" wheels, please tell me what wheel did he buyed it.
thank you very much, and a special greetings from chile
