Suggested tire sizes for 18x10+10 and 18x11+11? I'm on coilovers and will be sitting quite low, my guards also haven't been rolled but I'm guessing I'll need to change that. 255/35/18 and 285/35/18 is what I'm thinking.

^ That was the setup I was looking at. You will need to roll.
Tire calculators are telling me I've messed up, but I did the maths myself from the numbers on Nitto's site and it seems to work?
Everywhere says 245/40-18 and 275/35-18 will set VDC off, and it appears tire calcs say the same (front is taller). But according to Nitto's numbers on their site the rear will be taller and give me a 0.15% difference between rear and front.
Might start out OK and then change as the rears wear down and the front does become taller?
Now I might just put the 275 on the front and go 295 in the rear like originally planned.

255/35-18 is never a good size front, at least step up to a 265/35 front

I'm gonna see if it works, because the numbers show that they will. I'm not asking permission, I'm asking to step away from the online calculator and look at the actual specs of these specific tires.
If not, guess I'll put the 275 on the front. I'm not putting a 275/40 on the rear... as previously discussed my feelings of how it looks.

I've been running 245/40 and 275/40 for many years for autoxing and road courses w/o any issues. Now the issue is what brand tire you use. I'm running with Sumitomo HTR III's now and love them.

This is a 245/40 and 275/35 setup.
Tires are Nitto NT05
Ignoring the online calculators which tell you the setup won't work and looking at the numbers from Nitto's site:
The front diameter is 65.0 cm
The front circumference is 204.3 cm
The rear diameter is 65.1 cm
The rear circumference is 204.5 cm
Although not a big difference, I'm just wondering if it's enough to keep VDC happy. If not, its not a huge deal... tires can be swapped around pretty easy. But these are what I have and might as well run with it.

I'd rather go 295/35 in the rear and throw the 275/35 up front. 275/40 is a full inch taller than what I'm running with the current 275/35. I just don't think it would look right on my wheels, but some can pull them off nicely.
Lol, I'm just gonna find out how it runs and report back. If they need switching up then I hope the 295's are here before the next meet up.

No VDC issues so far just driving around the apartment. Hoping to get to drive it down the street here shortly...

You probably won't have any issues until you push the car a bit, like doing an emergency maneuver or something. The wheels alone look cool but I'm not so sure on the G. BTW, what did you do to your exhaust?

Exhaust is left over from the Gram Light days. I just haven't gotten around to unbolting the extension. Car sat on jack stands for 5 months. I was eager to get the wheels on and drive it around a bit 
I'm still relatively new to Fort Worth, Tx so I need to find a reputable muffler shop to weld me just a regular pipe on there.
