Link to an article with actual brake stopping distances. It not just brakes but the entire package including tires to really get the braking performance up. But front disks plus decent radial tires should get 70-120 feet better stopping distances from 60mph.
Stock brakes are poor at 250-300 feet from 60 mph........don't kid your self.......250 a perfect stock system is not great braking, it's just barely getting by.

This stock mid 60's truck started at 60-0 at 266 ft after the upgrades it was 176 ft.
