Tyre sizes sound fine.
Depending on which wheels you run at the rear, you may/may not have enough inner clearence to the rear trailing arm. (I'm not 100% at stock height)
Fully lowered, I've previously run a 16x8.5 +37, which was undriveable as it rubbed against the trailing arm. With a 5mm or 3mm (can't remember which one off the top of my head) slip on spacer is just cleared but scrubbed under very hard cornering.
Previous to that I ran 16x8 +38 in the rear, which just scrubbed against the trailing arm under heavy cornering. Wasn't even enough that I noticed it on the day.
