I would be interested in trying a slotted rotor for an 82 320i. How much do you charge. Slotted is more but ones rotors stay a bit cooler and that is desireble. If the price is right then I will hold my breath and try your out. Mine are warpped at the moment and i was pondering over slotted or not? So if you would, or i will try tomarrow also 1-715-962-4666, call and thank you for your effort
