I do not have ABS, I can lock the brakes if I want to, I have not done it yet being that I have not driven enough to completely break in the disks and pads so I have not used them severely yet, I do know however that i can lock them up. The largest benefit that I have seen is in the ability to modulate the brakes with little effort, I can easily modulate from light clamping to full lock up, something I definitely couldn't do with my oem brakes. my wheels weigh 16.5 pounds each, that is about half the weight of a stock 16 inch wheel.
