OK, now I'm all for safety, but I really doubt that a rotor that is
.04 less than the manual says will make that much difference in
the majority of driving situations. If the brakes on the Spitfire
are working OK (Do they feel OK? When braking, is there any
noticable pulsations felt on the brake pedal?) If not, then I'd
leave the rotors alone as long as you don't plan on entering any
long distance endurance races.
Just my .02 on the subject, having driven many cars with scored rotors,
etc.
