These cross-drilled & slotted rotors are a performance upgrade option for your Sprite/Midget. Under hard use the brake pad surface emits gasses which cause the pads to plane over the surface of the rotors. The grooves in these rotors channel the gasses away from the braking surface and reduce brake fade, while the cross-drilled holes assist with heat dispersion. The grooves also reduce pad material build-up on the rotor surface and minimize glazing. Sold in a left-hand/right-hand pair.
