IRS rotor type

[FMJ]

I have a MK4 complete kit with IRS and would like to change the rotors to a slotted version. Are the brakes supplied for the IRS from a Ford Thunderbird SC in the late 80's early 90's vintage?

Hi,

The IRS brakes that we give in the complete kit use the 11.65" rear rotors from a 03-04 Mustang Mach 1 or Cobra. The center section, spindles and hubs, and brakes can all come from a 90's T-bird, MK8, or Cougar. The complete IRS from us that also comes with the center section, spindles, hubs, and brakes, is modified in the fact that the bolt pattern is 5x4.5. All of the donor car type components were 5x4.25, so rotors from those vehicles would not work on the complete kit system.

Thanks

So in short, I need rotors from a 03-04 Mustang Mach 1 or Cobra.

Thanks...
