Rim size??

I was wondering if 17x10.5 or 18x10.5 will fit my 2002 Mustang GT. I want to put a wider rim on the rear but not sure if a 10.5 will be too wide. I dont want the rim and tire to stick out of the fender well, I just want a plush look. Anyone who can offer any assistance is greatly appreciated. Thanks

Sorry to respond so late, I hardly visit this part of the forum, but anyway, those 18x10.5 will stick out a little bit. I would put 18x9.5's and call it a day!

Thanks Mars I appreciate your help.

I'm not sure about 10.5" but I know you can definetly put 10" wide on the back Rousch and Saleen do.

i was thinking about 18 8 10.5 bullitt dished wheels for the back of my 95 gt will those stick out?

#1 Depends on the backspacing of the rim...

#2 There will have to be some massaging of the inner fender, nothing a 5lb sledge and a lil careful hitting can't handle.
