More fluid flow is needed in order to move the calipers the same amount as the stock 240 calipers. so, in order to solve this problem i would recommend getting a 15/16 MBC instead of using the stock 7/8 MBC that you have right now. This will give you a stiffer pedal and better brake feedback. good luck

Gotcha. See, that's what I was thinking, but I thought I read that people who did the upgrade didn't need to change BMC's...unless maybe it's personal preference as to the softness/stiffness of the pedal.
I guess it's back to using a 86 S12 BMC like I had on my old s13.
Semi-edit: I just realized that I didn't extend the adjusting rod (lodge a bar to make the brake pedal pressed or get someone to do it) before trying to adjust it. So you're saying that adjusting the rod won't help at all and I just need to upgrade/change the BMC?
