The speedometer will be off. It will look funny.
Pros/Cons depend on the reasons for doing this, though.

I run 235/45-17 F and 245/45-17 R on my '06 and have around 100k miles with those size tires. Car looks better, tire fills the wheel well. Let me tell you how I wound up with those size tires. We were on vacation and I ran over a bolt that went into my half wore rear tire. Could not fix the tire and the town we were in(Elma,WA) only had one tire shop in town(Les Schwab) and 245/40-17 is a tire they don't stock so 245/45-17 had to be put on the S or miss 2 days of vaction. The VSA works way to soon with the 225/45 245/45 mix of tires so drove with it off most of the time.
I noticed right away that the car road smooth(less harsh) and when we got back from vac. I had a choice to make, new rear tires or go taller up front. I went taller up front and have been on the taller size tires for years now. I don't track my S but I have put a hell of a lot of miles on back roads that cover 13 states and I get a better ride with more traction with this size tires. I have a real hard time making the car push coming out of a turn with the 235's up front and the taller rear tires seem to hold better than the stock size tire. We are only talking about a tire that is 1" taller than stock out back so that would raise the car 1/2"
I did add a C/R front sway bar to my S but I was going to do that whichever tires I ran. I ran Continental DW tires most of the time but I'm on Fierstone Firehawk Indy 500 tires(just got them) and like them to.
Here is a pic from our 3 week trip out west and the trunk is packed so its sitting a little lower in the back than if we're going on a day drive.

Sometimes this can cause rubbing issues depending on your ride height. Why would you be looking at running the taller tire? I know some people wide up with it due to wanting wider tires and the wider you go it gets harder to keep the diameter the same.

Like I said in my post, my '06 is all stock except I added a C/R front sway bar. Front tires are 25.4" tall and my rears are 25.7" tall and in 100k miles I have not had any rubbing problems with my tires. This is on stock wheels.
Here is a pic of two S's DR Brod and my S, his is on standard tires and mine is on the taller tires. doesn't look like a monster truck to me

Looks are subjective, personally I don't mind smaller wheels with taller sidewalls visually.
Other downsides:
more rotational and unsprung mass.
taller overall gearing (equivalent from changing from stock 4.10 diff to 3.94 ratio)
More compliant sidewall, less responsive turn-in
speedometer/odometer error (more so odometer error, as speedometers usually read optimistically high with stock tire OD)
Plenty of great tires available in stock diameter, why you wanna go taller?
