  6. Wheels, Tires and Suspension
    Wasn't sure where to put this, I did a drum brake search with no results. Just replaced my stock rotors on my Optima with aftermarket cross drilled and slotted rotors. When I pulled the rear rotors off there were drum brakes on the inside of the disc brake rotor. Essentially it has both disc...
