It might need a small spacer.
The rears should fit no problem.

They'll work, but it'll be close, but not as close as my street wheels. I'd have to say a +40mm 17 x 8.5 is as close as I'd want to get (mine). So i do a quick calc-measurement and I think they'll work... Like Ted says, there are spacers
Where do ya find 1-4mm spacers? I got my 5mm at the rack
anyone?

We got a set of 3mm ones.
Probably off-brand, made-in-Tawian crap, but how advanced does a spacer got to be?

I had
235/40/17
17 X 8 +35 RPF1, cusco zero 2 coil overs and I had to use a 3mm spacer on the front to make the offset +32 so it would clear.
255/40/17
17 X 9 +35 RPF1 rear was not a problem at all.

I think I figured it out...
I got to mess with a set of Tein RA's, and they had adjustable height by adjusting the shock body rather than changing the lower spring perch mount.
It could be possible to jack the shock body to allow the lower spring perch to clear the tire sidewall, allowing at least another 1/2" of clearance.
So, if the lower perch can clear the the sidewall, this is where the extra offset is coming from.
Not all coilover kits are designed like this, so it's dependent on the type and brand of coilovers.
1/2" = ~13mm
So all this to the +30 8" spec, and you get the +40 to +45 offsets!
Ah HA!

Front Wheel Fitment
I have been reading the thread and am in the process of deciding on what i would like to buy for wheels. RETed,raising arizona can you guys take a look at the chart and let me know if these numbers are correct or at least close enough to use as a guide. The "dish" field on the far right is the amount of rim that will extend out further then the OE TII wheel. These numbers do not include tire sizes

Photos of Front Wheel Measurement
I took a few pictures of my car while i measured for wheel fitment one image is from mounting Flange on the hub to the strut/spring and the other os from hub flange to fender. Using the 5" backspacing (for safe usage) the 7.5" width rim is about all you can fit with out rolling the fender. So a 17x7.5 with a +32 offset is the best fit with out modification and you could use wheel spacers to "flush" up the rim to the fender

Stock FD rims are the tightest fitting without spacers, and those are 16" x 8" +50.
If you run those numbers, it's exactly 6.0" of backspacing.
Nice chart!
It's a bit confusing to read at first, but if you stare at it long enough it has some nice data.
The only it does not have is clearance to the outside fender edge.

One more time with rim to fender measurements
thanks for the input Ted, i added the rim to fender clearance numbers. The numbers are the actual distance from the rim lip(estimated as close as possible) to the inside of the fender lip...for example the 8" wheel with +25.4 offset would stick outside the fender and you would have to either add camber(if you have adjustable camber), roll the fender or use wider fenders...where the 7.5" wheel with +31.8 offset would be inside the fender by a quarter of an inch....hope this makes sense

As I've said before, the +40mm 8.5" has to be the tightest on the inside there is, of course depending on coils, camber and tyre manufacture plays a huge part... I think an 8" is the way to go simply because a 235 is probably max on the front so why go wider wheel... ya know? I'll tell you first had my front rim is tight, but it doesn't rub...
great work Bastard! Got a name? I hate calling you a Bastard when I hardly know ya heehee
