What are you trying to acheive by running such a wide wheel? You'll certainly loose acceleration, steering response, and fuel efficiency. Plus, you'd probably have to cut the fenders quite a bit to prevent rubbing. Rolling and pulling the fenders would probably not be enough, especially with those springs.
A 10" wide wheel with a 25mm offset is going to stick out like crazy and look like s***.
Word, stock 7" is et53 so although the offset will end up to be close, I've tried a 9" is the biggest you can tuck even stretching your tires.
