All new reproduction of Sumitomo's discontinued alumimum two (38.1mm) piston rear Z32 300ZX Twin Turbo calipers (These are not reman calipers). These popular calipers bolt diectly to lots of 90's era Nissan Models such as S-chassis, R-chassis, Q45, etc, as long as you use the 300ZX TT rotors. Finished in gold paint with laser logos. Sold as a pair of left and right calipers with pads included. We chose to include brake pads that lock up hard when brakes are cold, which is perfect for handbrake use in drifting. Use these calipers with 1995 300ZX TT 18mm vented twin turbo spec rotor from your local autoparts store. Lots of information is available online http://importnut.net/300zxbrakeswap.htm about the other parts you may need to perform a complete brake system upgrade. We manufacture adapters and dual caliper brackets for use on many non-Nissan vehicles such as E36, E46, RX7, and GT86 using our rear drop knuckles. ~**ALWAYS MOUNT CALIPERS WITH THE BLEEDER ON TOP . Does not include mounting bolts.
