Tire width Tech. Question???
Can any one please tell me, is it important to choose a wider tire in the back than the front when, upgrading my wheels to 20's.???????
Or can I just select the same size width for all four tires???
Thanks....

Usually the goal when upgrading to larger wheels is for performance, handling and looks. When you go with the wider wheel in the rear, you're most likely going to go with a wider tire as well. A wider tire means more surface contact with the ground where as a narrower tire has less. The more surface contact you have with the ground, the better your traction and handling capabilities become. Since the the GS is a rear wheel drive car, it only makes sense you go with a staggered wheel set-up that has wider wheel set-up in the rear.
ie-a 225/35 is about equal to a 245/30
thats why guys who run a staggered setup have slightly less sidewall on the rears, because they'r running wider tires.

I just try to constantly remind people that its a aspect RATIO, the operative word being RATIO or proportional relation.
To the original poster, there is no one set right tire setup, it all depends on the wheels, the specs of the wheels, the lowering, etc etc etc.
Its amazing that after all these years people still think the aspect ratio is a independent measurement! A wider tire with the same aspect ratio will be ALOT taller than the front!

Now that everyone has pointed out what the performance benefit of running staggered, I'll tell you the asthetic perks 
Usually on a rear wheel drive car (RWD) the rear wheel wells/opening are deeper than the front ones. With the same size wheel, the front wheel will fill up the front wheel well/opening while leaving the rear wheel unproportionate to it's well/opening. I for one don't like seeing this, specially on a modded Lexus.
Also, it looks more aggressive

You explanation was pretty much spot on
reason being? the audi s4 is awd and aftermarket staggered setup are seen everywhere
from talking to bob (socalsc4), it seems like putting staggered setup on awd isn't a problem, as long as the overall diameter is calculated carefully.

meh, i was just going by what i know from WRX's and EVO's since most guys who seriously drive those cars keep all 4 widths the same.
