I have been looking a standard front rotors (not drilled or slotted) for my 01 Bullitt. Some are listed as one part number for both sides and some have part numbers for left and right. Are the rotors on the Bullitt's directional? Thanks!
The original Ford rotor for the 99-04 Cobra/Bullitt/Mach is a non directional rotor made by Brembo. Internal vanes are straight.
The rotor for the 94-98 Cobra is directional. It was made by a different vendor so the casting is slightly different.
That's why you see both options come up when you search for rotors. Some companies use the 94-98 casting and others the 99-04 casting. They are interchangible and you can use either on your car.
