Carbon-Ceramic rotors seem to be a good thing according to this article in the NTY:
http://www.nytimes.com/2010/08/01/automobiles/01BRAKES.html?ref=automobiles

Wondered if the the weight loss on the "un-sprung" weight of a R3 would be advantageous?

Anybody have any expertice in this area? Is the un-sprung weight (weight apart from the shocks) a problem or would lowering this weight have any advantages?

Just curious...

Less unsprung weight is easier for the suspension components to control.

Lighter wheels, tires, rotors, etc. require less spring strength and less hydraulic dampening in order to keep the front end in contact with the pavement. These are also reducing rotational mass, which improves acceleration and braking.

Carbon-ceramic rotors with carbon pads have excellent stopping ability, and no real heat build up. The only real downside is the co$t. But this is dropping every year.

BrakeTech has a CMC (Ceramic Matrix Composite) rotor that they claim is even better than carbon ceramic. Something to look into, but the rotors will set you back around USD $1100 each - $2200 a set.
 

Then it would seem that a 30 lb. (3 rotors at about 10lbs each) or so unsprung weight loss should add up to some marked improvement in what? Acceleration, handling, or ...

Not to mention the accentuated braking and the life of the rotors (never need to be replaced-as per the article).

I haven't weighed the front rotors on the R3... yet, but I expect them to be around 4 pounds each.

ALL 3 might weigh 10 lbs.

Okay, then the unsprung argument goes away and you only have left great braking and lifetime rotors... Not as good a deal

Thanks for the insight.
