The older Cobalt spec(VR) has similar torque to our current XR2 Carbon-Ceramic compound, but with slightly less fade resistance. It was used to win several races in Grand Am Rolex and Star Mazda between 2003-2004 in addition to numerous NASA and SCCA victories up to 2006. Still considered a very good medium-high torque compound even when compared to our current XR-Series materials.
