17"

Alright Guys,
Thinking about some 17"s for my Corsa, and ive been told some 17 offsets fit them, but does anyone know whether you can lower it with 17"s, without any wheel arch modifications?!?

Offset should be between 45 and 49mm, you can lower 30-40 on this without mods, or remove the arch bolts and return lip on the plastic arch and lower a little more.
