The Motul 660 and DS2500 will improve braking endurance but not reduce stopping distances. That is a common misconception.
The DS2500 has a similar friction coefficient to OEM pads. They give you no more torque than most OEM pads at an average of 0.42. Where you gain is in higher temperature fade resistance. Same with the Motul 660 fluid and the high 325 Deg C dry boiling point compared to a normal DOT 4.
Braided lines do very little apart from very, very small reduction in system fluid compression under load and better under body/arch flexible line feed damage resistance. Decent pads, discs and fluid are the first priorities.
