The PowerStop Evolution drilled and slotted front rotors for 1990–1993 Mazda Miata are a bolt-on upgrade offering improved brake cooling and cleaner pad contact. Precision cross-drilled holes and rounded slots sweep away gasses, dust and moisture while chamfered holes reduce stress cracking. Zinc dichromate plating adds corrosion resistance; rotors are dynamically balanced and match original equipment specifications.
