The PowerStop Evolution drilled & slotted rotor pair for 1978–1981 Pontiac Firebird (rear) is a bolt‑on performance rotor plated in silver zinc dichromate to resist corrosion. Precision cross‑drilling and rounded slots clear gases, dust, and water for a cleaner friction surface while careful manufacturing tolerances for DTV and runout and dynamic mill balancing deliver smooth, direct OE fitment without special modifications.
