Since the Enzo has Carbon brake rotors, you are probably correct. Also, they are not carbon fiber, they don't have fibers and they don't have a resin to hold the fibers. They are made like diamonds, lots of carbon, lots of pressure, lots of heat and lots of time. It takes about 6mos to make a carbon rotor, last I heard on one of the F1 interviews.

I would be amazed if somebody made a bolt on kit for much of anything with carbon rotors.

As far as an autocross car, you would not save 1lb per wheel by turning the rotors down to min thickness. Also, you will lose braking capacity, since the rotors aren't able to absorb as much heat as they were before.

Now if you were going to look at the difference between the 26mm and 30mm 300zx rotors, then you might have a point. If your car isn't really fast (stock) and you aren't racing at a super speedway then you will probably be better off with the 26m rotors. BTW, does anybody know the weight diff between the two, I am considering running the 26's for weight reasons
