I have a 99 cobra and was wondering what size tires and rims i can match up for the front and back. I'd like the front smaller than the back but as big as possible. Thae car has been lowered about an inch. Can I put 19's on the back and 18's on the front?

Go with same size front and back. I recommend 17" x 9"s up front and 10.5"s out back for yourCobra. There are some nice Cobra replicas that will fitvery nicely. Post this question in the SVT section (http://www.mustangforums.com/forumid_208/tt.htm) of MF's as well.

I run 275/35/18"s and 295/30/18"s out back on 10.5"s (with 1/2" spacers in back) on my '02 Saleen. Seems to me you have solid axle, so either size will work fine.
