Ok. I have a pair of 20" wheel in my rear, bt when i was tring to buy the wheels,i could not find any specs. on what can i fit my wheels. an i courent waite (worst mistake) no i had to replace one side of the rear fenders. So out with the old wheels an looking for new ones. My question is [/align][/align][/align]Can anybody point me to the right direction with this? Tring to put thew right wheels in the rear.(20" if i can).[/align]

 

the rear will fit 20" wheels, you just need to use a tire size calculator and size the tires properly to keep the closest overall diameter to stock. This way you wont have rubbing issues(also need to check offset) and your speedometer will be accurate.

here is a link to a calculator: http://www.1010tires.com/TireSizeCalculator.asp

 

These are the specs for my wheels.
backspacing is 6.25" 159mm
offset 1.5" +38mm
tires are 255/35/20
bolt patternis 5 x 4.5 inches 5 x 114.3 mm

 

[/align][/align][/align][/align]Thanks Prometheus Prime for the specs. thats what i was looking for. any chance u got a pic of ur setup? and what kind of wheel you have?[/align]

 

A 275/35 sits nicely on a 9" wide 20" rim. I also have the same tire on my rear 10.5" wide rims but think they look too "stretched" and so for that width will be looking to change up to a 285 or 295 tire next time. Car is lowered and no rubbing at all. Just buy wheels for the 2005 Mustang and you'll be fine.

 

I got them from our wheel vender but Americanmuscle have the same setup.
