Wheel questions
 

Hey guys, I´ve been checking out the wheel forums for a while, and wanted a bit of your assistance. I´m looking forward to buying wheels for my MS3, but have a few questions. I want to keep having 18 inch wheels, and want to go as far as 18X8, but dont know if it will rub with stock suspension. What width is the max I can safely go with? I´ve been searching but I see mixed signals.

Also, I´ve seen these wheels, give me your opinion. They´re both Rota´s

GR-A in steel gray in the following size 18X7.5, 5X114.3, +48

or

Tarmac 3 in the following size 18X7.5, 5X114.3, +48

If i could fit 18x8 without rolling I would also consider Rota G-Forces

Thanks for your advice guys!
