Get the bricks out of our cars!
With the calipers and rotors recently removed, I took some time to weigh them. Here's what I found:
Front caliper: 10 lbs
Front rotor: 14 lbs
That's 24 pounds of unsprung weight on each front wheel!
The rears are slightly better.
Rear caliper: 5 lbs
Rear rotor: 9.5 lbs
The total for each rear wheel is 14.5 lbs.
That's a total of 77 pounds for the car, all of it unsprung.
What's a brick weigh, and how many of them are we carrying around?
Can't wait to see how much weight dwb1's ultimate brake system will save!

I'm not sure if brakes and calipers is where you want to be saving weight. Afterall, if you want something to hold up (and be strong) in a car then it's the rotors/calipers. There's just so much energy that they need to withstand and disperse.
I'd pressume that it will be very hard to lose weight while retaining the "strenght" of the current rotors/calipers .... that is unless you go to some exotic materials which means that the price will be insane and the rotors/calipers will cost 1/4 cost of the car (just a guess here).
Despite that, I'm all for shaving some weight of the S2000 :-)

Actually, dwb1's ultimate brake system, through the use of lighter but stronger alloys, should substantially reduce the weight of the brake system without any compromises in strength.

The brakes, wheels, and tires are actually the best places to shave weight - not because they're necessarily the heaviest parts, but because they're unsprung. 10 lbs of unsprung weight is worse then 20 lbs of sprung weight.
