The J-hook design offers some advantages over grooved rotors; greater
initial bite, superior pad cleaning, faster pad release and reduced
thickness variation. The advantages that this provides are faster
reaction, less susceptible to glazing, brake drag, and brake pad
build up.

Note: We have tested these rotors with Hawk, PFC, and Brake Man
pands and found them to be worth the price difference over our
standard rotors.
