I have a spare set of front and rear callipers from a 93 model R32 GTR.
If you don’t know, these are four piston front and two piston rear, alloy callipers and are in good condition, except some moron ground the Nissan logo's off the front callipers to allow some ill fitting wheels to clear them.
Therefore, they are going cheap! Great upgrade for Silvia’s and other Nissans. These were on my car and worked fine. I will post pics soon.
Looking for $180 for Front and $120 for rears. Will separate or $280 the LOT.
Pickup available from Highett, VIC or willing to post for extra $$
