There are a few options to fit five-lug wheels and brakes to the FFR, one of them being the use of '94-and-up Mustang spindles, which were five-lugs from the factory. The added benefit of these spindles is their sealed cartridge bearing and "divorced" rotor. The high-quality bearing requires no servicing, and the rotor can be removed without messing with the bearing or dust cap. If you want to maintain the desired front track of the '87-'93 Mustang parts, be sure to use only '94 or '95 spindles. The '96-and-up are a bit wider, though they will work.
