New Racing Brake kit

Billy, you had mentioned that the tabs on the RB rotor failed. Have you also seen premature wear, or short service life of these rotors? This may be due to the composition of the rotors, as I have seen many types of materials used and the RB rotors have a very high ferrous, or iron content. I dont know metallurgy, but excessive iron, and/or the casting process may make the rotors more brittle, or soft.

Hey John,

Yes all the rotor tabs had a nice shear right where it connects to the rotor itself. It could be the metallurgy or the sharp angle/design of the tabs, or a combination of the two that caused them to fail during its only weekend of being tested. We did not notice any wear or any issues prior to the failure and we were checking them over every session as it was the first 2pc rotor we tried.

In regards to cross-drilled rotors, they prevent the pad from developing a gas 'cushion' that prevents the pad from biting into the rotor. Both X-drilled and slotted rotors 'clean' the face of the pad as well as prevent this gas buildup.

We use the stock rear factory X-drilled Porsche rear rotors on our Koni Challenge GS car and Tri-Point uses the X-drilled rotors from Stoptech on their World Challenge Touring cars, which last 1/2-a full season.
