This Big brake upgrade bolts directly to 2011-2016 Kia Optima or Hyundai Sonata. Increases rotor size from 11.8 inch to 12.6 inch while dramatcally reducing unsprung weight. Rotors are OGX brand slotted for improved heat management and weigh only 16 pounds as they use aluminum hats increasing acceleration and braking.
Calipers are dual piston 43mm each matching the original braking force. Caliper brackets are both painted to match rotor color. Brakes feel more solid and brake pad wear is uniform. These calipers are from HYUNDAI XG350 model and are direct bolt on.
Fyi. One caliper is painted and one caliper in unpainted. I intended to use in my Sonata but never completed install. This combo is worth over $1200.
