Thinking of getting some 18" Victor Innsbruck rims in matte black to put on my 2004 40th AE. This is a street car but I just hate the chrome look of the factory rims on the 40AE I have on now and being silver I figure would look nice in matte. I believe GT3 spec rims are 18x8.5 40mm offset front and 18x11 63mm offset rear and I like that look. The Victor website shows the offsets on the Innsbrucks as 45mm for the front and 55mm for the rear in 10.5" and 50mm in 10". Ideally, what size tires should I run? I currently run 235/40 18x8 50mm offset front and 295/30 on 18x10 65mm offset rear with ZERO rubbing issues. Car is stock height but I may wish to go with x74 down the road and I just don't want rubbing issues but at same time would love to fill out the wheel well. Car is an x51 2004 Anniversary Edition.

Should I go:

1. Innsbrucks at 10"x18" ET50 w/285 rear vs. OEM 10"x18" ET65

2. Innsbrucks at 10.5"x18" ET55 w/295 rear vs. OEM 10"x18" ET65

3.Innsbrucks at 10.5"x18" ET55 w/285 rear vs. OEM 10"x18" ET65

Car is an x51 2004

I used these wheel and rim offset calculators others may find them helpful:
