17" rims with 40 ET
225/45/17 tires and 225/5017 tires
Some 17"s will clear the stock brakes while some will not. To be certain you should just try one of the wheels on.
As for tire sizes, if you want a squared setup the correct tire size for 17"s is 225/50/17 all around. 225/45/17 is too thin of a sidewall.

You never mentioned the width of the rim, that is important too when you mention offset. If they are 8" you are fine in the front but you will need a significant spacer at the back to keep the wheel from being tucked under the fender.
