Hey guys. I posted this question a couple of weeks ago on forums.corral.net but haven't been able to get a response from anyone.

I need some input from the community about what wheel size would be best for me. I'm a gear head but I'm almost more of an amateur than a pro so please forgive me if this seems like a dumb question.

I have a '98 GT that I've owned for 14 years. I got into a wreck about two years ago. I decided the damage was too extensive and that I would rather start over with another '98 than try to fix mine. So I've purchased a '98 six cylinder. It's in excellent condition with only 50,000 miles on the odometer. I intend to do a 4.6 Windsor swap (99-01).

My intention is to swap the rear end with one from a 99-04 GT. These rear ends are an inch wider than those found in the 94-98s. My question is about what size wheel would be best for me. I see a lot of guys run 17 or 18x9s in the front and 10s in the rear. I'm assuming they do this to make the wheels and tires flush with the rear fender. If I'm using the wider rear end is there any benefit to running 10 inch wheels in the rear or should I just stick with the 9s? Part of me would prefer to do the 9" wheels all the way around so that I can rotate them, while another part of me really does like the dished look of the 10" wheels. I do want the wheels to set flush with the rear fender, but I don't want them to stick out at all. The 9" wheels have a 5.95" backspacing while the 10" wheels have an offset of +22 millimeters and backspacing of 6.37".

Any input would be appreciated!!
