And it will also increase rotational weight, lessen braking effeciency, decrease acceleration, screw up the speedometer, and reduce your rearend ratio,further reducing your take off "jump".
17x8 and 18x9 are huge wheels for our classics. Are you going to tubb and roll, or just jack it up and stick them out the sides and look like ghetto crap?

you really need to tell us what year mustang you have. 64-66 could not take as large of wheels as the 67+.
As far as the diameter of the rims- no, it is not just for looks. The bigger the rim will improve handling because it'll leave the tire with a smaller sidewall. Remember, the tire will flex on a turn, where as the rim won't. Thus less sidewall is more stable.It'll also make for a stiffer/rougher ride.Meanwhile, if you're looking for strait-line traction, the bigger sidewall will actually help get traction from a start.

2. increase rotational weight - because as we all know this aluminum 17 and 18 inch wheels are soooooooo much 'heavier' than the stock steel wheels.
3. lessen braking effeciency - ohh there's a biggie let me ask this, why? Is it because of what you think for #2 that they are heavier or for #5 that they are screwing up your gear ratio? I do know that with 17s I can fit some pretty beefy brakes on my car that I couldn't fit with 15s I would hate to think that I've somehow screwed it up so much that the big beefy brakes actually are somehow substandard to the stock 4 wheel drums that fit under a 13 inch rim.
4. decrease acceleration - You're stretching here and I'm not sure what for. When I went from my 15s to 17s my car got a lot faster...might have something to do with more traction since I can fit a wider tire on the car in 17s than I can in 15s. If you oversize your tire sure you can impact total performance but oversizing the tire is the width and height of the tire not the rim
5. screw up the speedometer, and reduce your rearend ratio,further reducing your take off "jump" - I'm going to lump this altogether for you. Stock mustang wheel outer diameter (this is the rim with a tire mounted on it) is just about 26 inches. 215 60 15 is just about 26 inches, 225 50 16 is just about 26 inches, 235 45 17 is just about 26 inches, etc...what do all these numbers mean...it means that a larger rim with the correct tire will have ZERO impact on speedo, gear ratios, and your 'jump'
Just serving to add some facts and some of my opinions to the other opinions here already. All opinions are valid obviously valid. If you don't like 17s on a mustang that is fine.
BTW - The sig below shows my 17x8....neither of these "jack it up and stick them out the sides and look like ghetto crap" seem like a valid description to me since the car is lowered, they fit under the sheetmetal with the only mod being that I rolled the lip in the rear slightly because I run a 255 40 17 in the rear...if I went with a matching tire to the front (245 40 17) I would not have had to roll the rear lips.

RE: width and size, do they matter?
Alright I am almost positive that i have decided to go with Bullitt Replicas (chrome) from American Muscle 17x8 in the front and 18x9 in the rear both with sumitomo tires. I thnk u guys a ton for the input.

1. The bigger the rim will improve handling because it'll leave the tire with a smaller sidewall - Just to be clear you only get a smaller sidewall if you put lower profile tires on the car. I know it is a moot point, but you don't have to put a 235 45 17 on a 17. There are plenty of larger tires out there...most won't fit on a mustang but they do exist
