you don't necessarily hafta upgrade the MC. that's one of the advantages of using the Q brakes. They don't displace as much fluid as the Z brakes....so the bias isn't changed as much. I would install the brakes first, and see how they feel. If the pedal is too soft, you can adjust the screw on the booster (turn it out a few turns) until you get the pedal feel you want.

If you feel the braking bias is screwed up, then you would need to replace the MC with a 15/16"....which i believe the Auto came with

K.. i have a buddy that can get me a M.C. from autozone for FREE!
anyone know what year z32 came with what M.C. and what booster? I am getting this for free. (one time only...) Anyone running a autozone,checker,kragen,napa mc or booster in their s13 or s14? how is their quality compared to a OEM? Should hold up about the same right?

yeah i got mine from kregen, they just rebuild the oem ones, just as good

besides you get like 2 year warranty or lifetime, i dont know which one, so you will be fine
