OK for your training as the ET gets smaller the outside edge of the rim is moving outboard. So the F&R rims are 1" wider than stock. That equals to 1/2" on each side. For the rears you have to add another + 15mm because the ET is going from 40 to 25. The bottom line is the outboard edge of the rear rim is going to move outboard a little over 1" and your rear tire will likely rub badly. The frt rims would probably be OK.
