03 GT Wheels offset?

Off the top of my head, the OEM wheels that go on 100% with no issues using the LMR kit are:

94-95 GT 17" Tri Bar wheels

94-98 16" "Waffle" or Pony wheels

01-04 Bullitts

If you hit the junkyards up and find an SN95 setup with the sealed bearings, you can run anything you want
 
Out of curiosity what is it that doesnt allow the centercaps to fit on with the LMR kit? Do the studs stick out too far or something?
Whats the difference between the SN95 setup and the Mark 7 setup?
 
All 17X8 Mustang wheels have a +30mm offset.

Those wheels will fit a fox 5 lug conversion. But the centers will only fit using 94-94 or 96-04 spindles.

Ryan218, used those wheels and Mark VII stuff, but he had to use a spacer, grind the inside of the center cap, and bang in the dust cap.

Don't go with a Mark VII swap. You still get crap fox brakes. Upgrade to 94-95 sindles, with 99-04 GT/V6 dual piston calipers.
 
Sadly I already have the Mark 7 setup. I would like to eventually upgrade to a better setup when but for the moment I would just like to have some 17x8s cus my 17x9s are a bit wide on the front. I would get the SN95 setup now, but I need to save some cash so I can take out my engine hopefully during the summer.
