275/35-18 is the correct size for a non-stretched application... to get those to fit, I'm thinking more around 255/35-18, which is a small stretch, but stretched none-the-less... I'd do 255's on a 8.5 or 9" wheel and be happy...

Well there ordered I got the Piaa Super Rooza 2P 19x9 +25 and 19x10 +25. So I can run a 275/35 with rolled fenders in the back, and 245/35 in the front?? Will post pic when there here. Thanks

Some of you guys perhaps still need to understand that offset is very important to determine how the wheel sits. If you really read ... I mean really read this thread from the beginning, then you should have gotten all. 
Anyways, here is a little illustration about offsets, taken from planetsoarer.com
An offset of +50mm means the wheels sit closer to the centre of the car than an offset of say 30mm.
+30mm offset wheels will stick out further and give the car a wider track.
So what's the big deal.
Going from +50 to +30mm offset changes the scrub radius. The entire geometry is designed around an offset of +50mm for a 7inch rim.
Lowering the offset, making the wheels stick out more, will change the feel of the steering. It will make the steering that little bit heavier and hitting bumps can kickback through the steering a bit more. The car will have greater "turn in" - it can give the steering a sporty, more involved feeling.
For those who want a proper fitment without running a negative chamber, I think the best offset for the rear is +35 on a 9.5 wide wheel ---> you still need to roll your fender. A Mild roll I should say.
If you went with wider wheel, such as 10 inch wide with offset >+35, then you need to shave/roll your fender and also pull it a little. You probably need to run a stretch tire.
-----------
I personally don't like stretch tire and the look of how the wheel sits like this /__\ .... and I don't think that is a proper fitment!
IMO: It looks ugly --> no offence for those who are running their SC like that.
-----------
Here is Hoebag SC300 with 19x10, offset +18, and he is running a 275 tire on it.
Look how his wheels stick out. He also pulled the fender.
It looks awesome!
This is what I call a proper fitment
-------
If you don't plan to roll your fender, then go with the higher offsets.
If you'd like to achieve a flush look, then go with 9.5 inch wheel with +35 and remember to roll your fender once you drop your SC!
This is Mitsuguy SC.
He is running 275 tire on a 19 X 9.5 wheel, offset +35
In my book this is also a proper fitment.
Dropped a little & a mild roll.
---------
From those 2 pictures above we can see the difference between offset +35 & +18
and don`t forget ... Hoebag's wheel is 0.5 inch wider than Mitsuguy's.

Yes I made a mistake, I guess I was too sleepy last night when I read your thread.
I knew your rear fender required a body work to fit those wide wheels.
You did it right!
I was trying to make a point that a wide wheel should be fitted a proper tire size and that wheel should sit straight. A lot of guys are trying to get a flush look and at the same time are trying to get wheels with a big lip. Just because they don't know the offset, then they will end up running a negative camber to fit those wheels under the fenders after the car is dropped. The result ..... the wheels will sit like this /__\ .
Perhaps one will be disappointed because his/her lack of knowledge about wheel width & offsets.
BTW, there also another CL member with a red SC from Illinois who has 11 inches wheels fit properly in the rear without having a lot of fender work. I forgot his name.

Well I apologize, folks.
When I get home tonight, I will search some more pictures.

Hey guys i got some GT-C's and some tires.
18x9 +31
18x10 +30
The tires that came w/ it are 225/40 and 245/40 and i rub a bit in the rear
The tires i want to put on are 245/40(fr) and 265/40(r)
I went to check out wut i can do. The guy suggested that i shave the rim in the rear to make the offset +38. Is it a good idea to shave the inside?
And i will end up cutting the rear fender.
For the front he suggested he shave 5mm making it +36
Wut's ur opinion on shaving the hub of the rim making it +38 and wut should i do about the fronts?
