Matt you're probably right...but I have a few thoughts on this. First is master bore size is one of those dial in things. If the first one doesn't give me the pedal feel I'll up or downsize. Secondly, master sizing is a function of fluid requirements for pistion bore size (sq area). On the Baer's a 15/16 or 1" is reccomended. C6Z's reqiuire 7/8" according to Tobin; I'm not sure what the prefect size is for your Wilwoods. Smaller bore moves more fluid and has more pedal travel in theory. Either way, balance bar goes way up front as you said.
So the goal is not to have a spongy pedal. I'm also going to call Baer on Monday and seek Rick's input.
I'd love to hear other's thoughts on this as well
