im pretty sur if you put mazda rear seals and bearing in the yoto rotor and shim your calibers they work buddy off mine did that to his and its been roolin since 2000 likw that
hey if you change the bearings and seals to mazda with toyota hubs and rotors it might not have bump steer but iotaf you change the mazda spindle to toy spindle you will have bump steer because the steering nuckle is diffrent. correct me if im wrong.
