RE: need help real quick
Different backspacing is different backspacing, no way around it.
Some have used them, but I have read that this is hard on the bearings.
If it was for the 2005, It would be under the 2005 wheels.

RE: need help real quick
The 2005 Ford Mustang GT has a +45mm Offset wheel from the factory. The allowable Offset is +19 to +65. A nice looking range is +30 to +45 Offset.
THIS ASSUMES you are still going to use an 8" wheel. All you had/have to do is measure the BackSpacing(BS) of the stock wheel. Then decide how much farther out you want your new wheel to stick out from your stock wheel. Subtract that from your stock backspacing. This is your new Backspacing that you will need on your new wheel. You might ask, what about OFFSET? If you have one you can caluculate the other. Remember back in High School that class that you thought was "useless and you will never use this stuff."
OFFSET = (OVERALL width - BS) / 2
Example: (9" - 5.75) / 2 = 1.625 " OFFSET
The OVERALL width on an 8" wheel is not 8". For example it might be 9" or 10" or 9.75".
American Racing Torq Thrust II will require a minimum BS of 5.5" on an 18 X 8 wheel.
I have gotten only 1 qoute in my area so far for AR Torq Thrust II Polished. $325 per wheel. 4 to 12 weeks.

RE: need help real quick
Based upon my posting. And my posting only. I would say NO. They will not fit. But,...................
Do you have quick access to a Discount Tire? If so, call them!!!
Now I should say that they will fit, but may not have the important look that you want. Just about anything with a 5 X 4.5 bolt pattern will fit, but it may not look good.
The +12mm OFFSET on the 18 X 9 wil really bring the wheel out of the wheel well.
My guess ta mut would be that the wheel will stick out about an inch from the stock 8" wheels.

RE: need help real quick
nobody is addressing the wheel bearing issue again!
read this and pay special attention to the "Note" under the offset section, this should not be overlooked! all you have to do is look at the bearing placemnet in the wheel and imagine a little leverage as you turn and think of the stress applied to the bearings

You are 100% correct!!!
In a nutshell if you draw an imaginary line from the center of the top spindle pivot to the center of the bottom spindle pivot and continue this line to the ground, it should coincide with the center of the tire footprint. If not, you WILL have stresses placed on bushings, bearings, and ball joints. THIS IS CALLED THE SCRUB RADIUS.
Of course, kids (and adults too) with lots of money don't really care about this stuff. Because they have money to repair the items that WILL cause problems in the future. The same holds true on the subject of lowering their cars. Some think I'll just add springs and I'll be set. There is more to it than that. I was told by someone on this forum that "ANYBODY" can do it, just take it to a mechanic. That summarizes it all right there. A lot of people do not understand what they are doing to there cars. Can it be done? Sure, but you better know/understand what you are gaining and what you are giving up.
Some here on this forum do not even know what a Panard bar is not alone what it does. However, they may be learning after they have already spent the $$$ on lowering their car. And that is part of tinkering and learning but at a cost.
That is what is scary about reading some of the things here on this forum. There are people doing things to there beautiful cars that they have no idea how they are affecting the engineering.
Anyway, it's still fun to talk about how cool your car looks though.[8D]
