Front Caliper Clearance - 20x10.5 (40 offset)?
 
All,

I am purchasing a set of 215 replicas for winter use. Current eBay sets are as follows:
20x9.5 with a 45 offset (front)
20x10.5 with a 40 offset (rear)

The OEM rims are as follows:
20x10 with a 40 offset (front)
20x11 with a 37 offset (rear)

Instead of doing a staggered setup for the winter rims and tires, I am looking at buying a square setup of 20x10.5 with a 40 offset for front and back. Using online offset calculators, I know the rears will sit in about .5" more than OEM, which should be fine. The fronts being .5" wider and having the OEM front offset should add .25" to each side of the bolt. Going outwards is fine, but the .25" inwards is what worries me. Do you think I'll still be able to clear the brake calipers to get this square setup to fit?

Isn't the wheel (and specifically, spokes) design the main factor to clear the calipers, while offset primarily determines the wheel well clearance and overall suspension geometry?

Yes, offset alone does not factor in if it will clear brakes or not, although it can help.

Glad to see you got them mounted up! How is the fitment? Sunken in, nice and flush, etc?

Correct, spoke design has a ton to do with wheels clearing calipers.
