What is the diameter of an early Fox body 4-lug front brake rotor? Did the GTs come with a larger 4-lug rotor?

'79-82 have 9.15" front discs (except for the '79 V8 Which had 10")
'82-85 have 10" front discs
'86 GT's have 10" front discs
'87-93 V8's have 11" front discs

Does that help?

FYI, you cannot swap rotor size without swapping spindles also.
