93-2002 Camaro/Firebird Pro Stop Power Slot Rotors, Select year and application, shipping is not included Designed for the performance enthusiast who wants the "look? of a cross-drilled brake rotor, but without the inherent problems, "ProStop? gives you the best of both worlds. In addition to the highly effective Vac-U-Slots that dissipate heat, these rotors are enhanced with a series of "dimples? that look like drilled holes but are only as deep as the recommended minimum rotor thickness. In other words, the structural integrity of the rotor is not compromised, as it would be if crack-prone holes were drilled. The faux-drilled treatment adds to the look of the rotor, as does the brilliant silver cadmium plating. On the performance side of the equation, ProStop rotors are designed to run cooler, improve both wet and dry braking, and have outstanding reliability. All ProStop rotors are made to the same quality specifications as the original Power Slot line.
