Hi, I use the Brembo RCS 19 with the Galfer Sinter Pads and the OEM Disks for one year now, 3 Racetrack Weekends included. With the Upgrade you will get a accurate pressure point, but you need more strength to recieve the same braking force. My personal impression is that the additional strenght now directly goes into brake force and not into a "spongy" pressure point.
