Have had 2 sets and they have excellent stopping power.
They heated up my disks which follows from track-braking and disks needed major cooling down. Probably mostly down to the driver. For rallies and sprints, there is more cool-down time between corners, so less hot disks.
Highly recommended.
(Have TS2000's now, and previously 2 x Lucas, 2 x EBC Redstuff Ceramic, 3 x Bendix Ultimates, not in that order.)
