A Few of X8 members ask me how to do it,and Its really easy,u only need a washer/spacer
or u can custom it at the foundry shop,but make sure the measurement is right between disc/rotor and the adjustable..
close up,hehe a little bit rusty...
some adjustable have a disc cover,but since the nissan 4pot is quite big compare to the stock 1jz brake,u can either cut it or throw it away like me hahaha....
here's the measurement
