I ran CC-RG before on the Brembos on a previous car.
They held up well under the track heat, incredible braking torque at any brake temp but squealed like dying pigs on the street. I've had a better experience with Project Mu pads for hybrid street/track use.
Here's a review done by Option Magazine. They were developed for WRC and Touring car racing.
