Best sized spacers for stock wheels

Until kid has money for wheels we have been trying to figure out best spacers to bring stock wheels as flush as possible with fenders. Stock wheels on stock ride height on 2011. From researching and some YouTubers it seems you can go with 25mm spacers at all 4 corners with no issues or fender rolling needed. Anyone out there able to confirm this?

 

If you go that far you need to get longer studs

 

I know rule of thumb is anything over 5mm you either need longer studs or longer bolts depending on application. He sent me a link to these:


Amazon is confirming fitment on a 11 MS3. Pattern and bore are correct. I think these would work...I think.

EDIT: Just noticed those are 20mm but they do have something similar in 25mm:
