I have been running RDA Slotted and dimpled rotors since 2006. Done more laps of Wanneroo than I can count and never had a problem with them. Drilled rotors are the ones to worry about as they stress and crack around the drill holes. My original Brembo rotors lasted 9 laps of Wanneroo before cracking up. And Hi everyone, Been a while since I was here. Still got the ute and the BFII XR6T
