I never weighed them, but according to ECS they're 4 lbs lighter per rotor, for a 8 lb front unsprung weight reduction. I like them a lot and they pretty look good when not dirty/rusty from sitting. As far as performance goes, I have no complaints with aggressive street driving and decently high speeds. I won't be using them at the track however, as they're a true drilled rotor which are prone to cracking due to thermal stresses - I'll be getting separate solid non drilled/slotted rotors for the track days later on.
