you wont gain any significant hp
but you can rev higher more safely and the engine will be way more responsive

DUDE,you really have to RE-read the INFO.
they take One pound OFF,so the Rotor is now 8.7 pounds,not 9.7 pounds(stock).
when I read your post,I thought Holy Crap!..they are Making the Rotors Out of Tin Foil!

Yes it will have a benefit, and if you can afford to put them in your car more power too you. However this mod is obviously very expensive and there are many other things you can do to your car that have the same or better benefits for a lot less money.

You would be better off Just Inflating your tires to 50lbs and greasing up your wheel bearings and Wax the car.

The engine will rev higher and be more reliable at those speeds. An increase in throttle response is also a result. However you will make less low end torque due to less rotating mass.

This is really a race modification only for aggressive ports like full bridge or peripheral. This is mainly an NA mod, since turbo engines don't have to rev up to make power (just turn up the boost).
