these are front calipers pulled from my 1990 300zx because I upgraded to the turbo calipers. Calipers are in good condition and comes with attached brake line and brake pads with some life. Also have rotors to go with calipers. Calipers are aluminum & i hear are a great brake upgrade for 240sx. Price is $140.00 plus shipping for calipers and rotors or $120.00 plus shipping for calipers alone. I can be reached at b7rian@adelphia.net. Thanks.
