I have xxr527 16x8 and 17x8.25
Tires are R888R in 205/45/17 and 235/40/17
The xxr527 has pretty aggressive offset (+20mm), and NEEDS a 6mm spacer to clear the front calipers. Puts you at +14 offset. You WILL NEED V2 arms and -2* camber.
Now put a wider 215 tire, and you should be fine, but i highly doubt it offers much more grip, and i doubt you actually need it. Just adds weight, money, and potentially rubbing.
You also cant go too low with this setup. At least I didnt. I would hate to see what happens if the front clam eats up the wheels during a deep compression.
