I need to get new brakes soon, and was thinking about getting a brake kit:

Would replacing with lightweight rotors translate into meaningful increase in gas mileage, and save meaningful amount of money on gas?

here's what I was thinking: the "OEM Big Brake Kit - Rotors by ECS Tuning (front)" is advertised as 23% lighter. i'm sure that performance is there, but with "normal" driving, will that equate to cost savings on gas?
