It depends how low you go, the front arches will need rolling for sure and you'll probably need 215 tyres.With ET47 on the back just 215 tyres should be OK but it will be tight, they might need flaring.
Rears with 215 tyres might stick out a bit and could need arches flaring to clear, with arches flared 5mm spacers might be needed to make it look even. Front will definitely need rolling and put some 215 tyres so it looks a bit more even.
