rear brakes bigger than front?

[stanglou]

I recently picked up an 8.8 rear out of a 2003 f-150. I was thinking of having is shortened and using it on the stang, but there is a delema. the rear discs on the thing are about 14 inches, which is bigger than my front wilwoods. will this look stupid? will it be functional? i got such a good deal on the thing that i couldn't pass it up.
