Master Cylinder went out.... Time to upgrade!!

Well, sadly and scary at that, my master cylinder went out today after going down a hill.... yeah...

needless to say I need to replace the old school 87 3port master cylinder with something that can better handle my 4wheel discs. I know I need to go with a larger piston, so at least a 94 gt cylinder for me. But I wanted to know just how much more stiffer I can make the pedal with the cobra version. I have a MM 3-2 port converter so I don't have an issue with this swap. I also wanted to update the brake booster as well. I don't want a huge cobra one. Whats the largest I can fit without cutting, whacking on the strut tower.


Before it is asked, I have cobra brakes, 13" dual pistons up front (38mm) and the 11.65" singles in the back. Proportioning valve is installed as well. I have no leaks anywhere on the car, so I have to say it's the master cylinder.


What do you guys propose?

So ideally yes, I would use the Cobra parts, however with the inability to find the parts locally, and with no time to wait, I will be going with the sn-95 pieces. I don't mind a harder pedal, as I was later on going to go with the Manual brake setup from MM. So I feel the larger bore will be a better overall investment now.
