wheels for 285 rcomps help
We run 18x10.5" +15 RPF-1's w/ 285/30/18 a6's on the VIII. Of course, it's running modified front fenders (similar to evodave's kit) and the rear fenders are pushed out a great deal.

I'm beginning to lean towards a staggered offset 15/18 in front and 35 or 38 and small spacer in rear.
That keeps me away from extended studs and spacers for now.
I've run 275/40/17's (mostly kumho v710 but recently hankook) on the stocker BBS's for 4 years in BSP (Las Vegas Region SCCA) PAX winner 2009, 2nd place all other years. Pinching them on those 8"wheels does slim down the true contact patch however. Didn't need to run spacers, but there's plenty of inner fender rubbing and trailing arm (rear) polishing...

The 10.5" wide RPF1's are pretty light too. The pair I weighed was lighter than Enkei claimed by a surprising margin.
The 285 Hoosiers are noticeably (10-15mm) larger on the 10.5's vs. 9.5's.
You can modify your stock front fenders with Home Depot parts and get more clearance than those wider cf fenders... plus the stock fenders are lighter.

the stock wheel is 8" +48 for an EVO 8&9
18x9.5 +30 is a good match
18x10 +24 works as well.
just remember that rubbing is subjective. How much can you live with? That answer will determine how much fender rolling you will need.

I run 285/30/18 Hoosier R6's
I have 18x9.5 NT03's +40
I run a 3mm spacer in the rear (to clear trailing arm) You also have to grind off the casting flash on the arm and trim to metal brackets so you don't eat your tire!
I run a 25mm spacer in the front to clear the brembos. Since I run a 25mm spacer...I can also run 4 degrees of camber if need be.
I rolled the fronts and the rears. I also had to clearance the rear ward pinch weld in the front wheel well. That means BFH + grinder + new seam sealer + undercoating. I no longer rub.
Also with that much camber...your factory brake line mounting point will rub your inner fender "frame" per say.
If you'd like to discuss all the modifications that have to be made... PM me and I'll give you my cell number to explain further.
I would recommend the NT03's...

I'd love to see some pics of 10.5s on the front to get an idea of how much work is involved.
If it looks reasonable I'd go with RPF1's 10.5 et15 front and 9.5 et38 rear.

That's what I have done this season. You need to have either very stiff front springs, or wider fenders for the 10.5's to fit without contact.
The 10.5" wide RPF1's are pretty light too. The pair I weighed was lighter than Enkei claimed by a surprising margin.
The 285 Hoosiers are noticeably (10-15mm) larger on the 10.5's vs. 9.5's.

I have 2 sets of 18x9.5" rims and I piled them side by side with the following mounted:
1) 9.3" wide 245 Hoosiers
2) 10.3" wide 255 Hoosiers
And.... #2 was probably 1/2" taller stacked at best. That's all 4 of them! Now there is probably more actual contact patch but I've been saying all year - get the widest rims you can!
Of course fitment becomes more difficult, rims get more expensive & heavier...etc.
I'd recommend against running different size rims/tires front-back. It's not a real good idea with full-time AWD. Just my .02.

The fronts are reasonable but still take the wider fender mod that you can put together at home depot.

With the 10.5" wheels, we use no spacers and +15 offset all around. (We stole these wheels from my X and forced the car to accept them.)
I will get a pic of the "roll" we did to the rear (it actually involved a big hammer and beating on it), but it won't be with the 285 a6's and rpf-1 unless you want to wait til september when we mount them back up for nationals. We decided to ensure they fit as the car has needed body work since the day it was bought, and all this will take to make look good is some smoothing work and a repaint that was already needed.

Wheels shown here are 18x9.5 +35(?) fn01r-c with 245/40, dd setup. The car looks like a sunken battleship with these wheels.
