need help on what MC to buy

i need to know which Z32 MC would be best for my brake setup. 30mm Z32 front brakes with stock S13 rear brakes.

you want the nabco one, not tokico

that much i know i just need to know what size i should pickup for a Z32 front and stock rear setup. i was told my Stock MC is no good and that i need something bigger.

why not try what you have first then decide if you need to change

and each model m/c has a particular piston size and rear bias, piston size is generally written into the casting

if you have stock Z32 brakes, the 17/16" MC is perfect… you don’t need anything bigger
