<< Trying to sort out some of the options for front brake rotors on the 3A. I
have been told that two different size rotors were fillted to the 3A. Both
are interchangeable and compatible with the 2nd generation Girling caliper
(16P?). Are there any other options for 3A rotors? Can the rotors from
the later 4s' or early TR6 be used on the 3? Wondering about this as there
is a considerable price difference among these rotors.

Could be wrong here but I believe the diameter of the early rotors is about
1/2" larger. So the TR4 rotors can fit with the earlier calipers but not vice
versa. Of course all the mounting plates are the same so an early rotor and
caliper would work on a later car, if installed together.
I'm going from memory so if wrong I'm sure somebody will let me know....
