TIRES 101!
-The Condensed Version…
Tire configuration is totally dependant on HOW you plan on driving the car.
Same size all the way around is the best configuration for "Passenger Cars"... Routine driving to and fro! No special needs, and simplifies the purchase the replacements as well as allows you front/rear rotation allowing you to extend the useful lifespan of the tires.
Since the car is a REAR Wheel Drive - you get better performance and handling with having slightly wider tires in the rear to provide the best forward traction. Narrow tires in the front to avoid “Scabbing in turns gives you quicker turning response. The sacrifice for performance is you will no longer be able to rotate tires, therein will shorten tire life causing you to replace tires more often. This will also cause you to keep tighter tabs on alignment of the fronts - End result is increased maintenance expense.
Wheel diameter configuration is based on the type of performance you want. Handling in curves or best grip on launch, or… best all-round launch and handling. The larger the wheel, the worse the launch the better the turns. The smaller the wheel, the better the launch, the worse the curves. Something in the middle (17’/18”) gives you a blend of both.
Compound also plays a factor. High Mileage tires use a harder compound and so don’t grip the road as well, giving you poor performance. Performance tires are very sticky but since they are made of a soft compound they don’t last very long.

RE: 18's or 20's
I agree, that is why I went with 255/45R18.
I found that a 45 sidewall is quite common these days and in factory trim a 45 tire is standard on many cars.
The 255 all around fills the wheel wells nicely without any rubbing issues and the slightly larger contact patch in the rear makes the car feel more stable.

Most tire manufacturers recommend 10" wheels for anything over 275s.
I have been doing considerable research on tires, and I have found 295/45-18 and 275/50-17 tires, but I don't recall seeing any 285/45-18 tires out there? I have also seen 285/35-18s, but they are too short (~1" shorter than stock).
So, which specific tire manufacturer makes 285/45-18s? I would love to know.

No one makes a tire in the 285/45-18. You can get a pirelli p-zero in a 285/40-18. I sell these tires for $204 each. They have 400 treadwear rating, Traction is: A, Temp is: A, and have a ZR speed rating.

RE: 18's or 20's
I'm running stock 17" 03/04 Cobras on my 05 GT and I love them...I'm also running 275's all the way around and it sits pretty flush with the side of the wheelwell. With 275's up front, it is a bit heavy in the steering, but it's not anything I cant live with...
here's a couple pics...
