The Power Stop Evolution drilled and slotted rotor pair is a bolt-on front upgrade for 1975–1977 Pontiac Ventura applications. Precision cross-drilled holes improve cooling while rounded slots clear gases, dust, and water to maintain a clean friction surface. Manufactured to tight tolerances and dynamically balanced, these rotors install without special modifications and are sold as a matched pair.
