Hi Bob, The front rotors on the Pumpkin are nearing the end of their effective life also. It appears there's a rule change in the works for the Spec. Cobras that will allow us to use the later spindles ('95 and newer?) that have a hub separate from the rotor.
That would certainly be nice. It will make changing out the front rotors a much simpler task.
After driving Pete Wison's Stang in the early '90s, I'm amazed these rotors have held up so well. Then again, I'm only stopping 2/3s of the old Stang's weight.
Best regards, Tom
