It has been more than 5000 miles since new with EBC Reds and no problems with many hard applications above 110 MPH.

That's a big HP number to toss around, especially for for a non power mod... While rotational mass does make a big impact, I'd like to see a source for this number...

Rotational mass, also known as kinetic energy. It takes less energy to spin up and therefore less energy to dissipate under braking.

It is a calculation which can be applied to any rotational mass. For example; look at the equivalent HP gains that are achieved by the replacement of engine crank pulleys with lightweight units as offered by various tuners. Usually in the range of a 10HP equivalence. Now consider the effect of a reduction of 40 LBS of rotational mass. This is partly why most exotics such as Ferrari, MB SLS, Porsche, to name just a few, all offer carbon rotors which save another 40 LBS or about 80 LBS. The MB SLS even utilizes a carbon fiber drive shaft (as do I) to reduce rotational mass. Years ago an acquaintance of mine said "add horsepower and go faster on the straightaways . . . add lightness and go faster everywhere". His name was Colin Chapman.

Learn more about the advantage on light weight rotors from "ML63"'s latest evaluation on his ML63 wit RacingBrake's two piece rotors (front and rear) installed.
