Hi Sasha,
the stock MC works fine…as it has enough fluid to work the stock brakes (in my case front z32 4 pot brakes and stock s13 rear calipers)
all you have to do is redrill the brake pedal pivot point so that you can exert more mechanical leverage on it…
if you want come up to ORF one day and test the brake pedal feel of my system…
with race pads on the track 100% its a very nice feeling system, that is non boosted…
PLUS you save the booster weight…and all the heat issues with having it near the turbo…thats why i did it…
what pads do you use? on the turbo s13 i used hawke ht-10’s and on the slower NA s13 us used hawke blues
