I recently swapped z32 calipers on my s13, i went with remanufactured calipers, new rotors, stainless steel conversion lines, and a used master cylinder(the only part i regret -__-).
SO, my question to you guys is, what aftermarket master cylinder did you guys use when going with bigger calipers?

Nevermind lol found my problem. But id still like to see what you guys use if it wasnt the oe z32 mc.

my problem with mine is that i forgot to add the flair fitting in the port that was plugged off

I have Q45 brakes and I use the stock ones. Feels the same but a z32 would be best for sure

Replace your "used" master's though. I would if I were you imo.

replacing it with new will happen in the near future, but right now i really need to make my used mc work. :/

you can rebuild your current one. rebuild kits are usually dirt cheap.
