For those who are curious to see what the unsprung weight savings convert to in terms of power.
1.3whp/8.1wtq gain from installing the rotors on a Mustang Dyno.

The advertised weights are actually a little heavy...16.5F and 13.5R. My new rotors weighed in at 15.8F and 13.4R. The front rotors saved me 4.4lbs ea and the rears saved me 3.6lbs ea compared to my worn Brembo rotors.
The GiroDisc rotors are true curved vane technology which helps with cooling and they come with anti-rattle springs for street use.
I'll do some track days (look at the color of my caliper), but mostly my Z is used for auto-x (2nd and 3rd at the Dixie National Tour). After a few events I'll post my impressions of the rotors and how they are wearing.
