The RC5+ is CL’s latest offering, and was developed with the autoX and track day crowd squarely in mind. It is a well-mannered race pad, with lower noise, low dust, and a lower coefficient of friction. The beauty of this compound is that despite its mild manners, it still retains a very high max operating temperature. It is a great choice for lighter cars on race tires, or heavy, high power cars on street tires. The failure mechanism of this pad is one of its greatest strengths. If you do happen to push it over its temperature threshold, bite slowly tapers away rather than falling off a cliff, so you’ll easily recognize when it’s time to back off. It’s extremely wear resistant, and doesn’t destroy rotors with pad deposits like the majority of street pads do when pushed to their temperature envelope. The RC5+ is a great rear pad option for those who like a more front biased setup with the RC6 or RC6E compound up front.

Because of their high metal content, CL Sintered Pads don’t rely on a pad transfer layer to generate high levels of friction. The only recommended bed-in after install is to do a few moderately hard stops to seat the pads flush with the rotor face. That’s it. When the pads heat to a certain point, they will deposit a layer material on the face of the rotors, just like other pad types. That pad transfer layer is extremely thin however, and contains graphite (a lubricant), which protects the rotors from wear. Because of the abrasive nature of the sintered material when cold, that thin transfer layer will quickly be removed from the rotors during any cold brake applications. The transfer layer of CL pads is essentially self-curing, and only develops when required to protect the rotors.
