For those of you who have converted to GT4 Calipers, looking for brake biasing information Options

[qatar11]

So I am going to switch over to the GT-Four Calipers, front and back and I have a question to anyone who has done this. What did you do about the brake bias? I have the ST205 valve... but it is plumbed for ABS so it is not immediately compatible with my current configuration.... Of course this thing sits behind the engine so the decision has to be made before I drop the engine in....

Let me know your thoughts.

would you be able to wait this weekend for me to tell you about bias the result?
I will be taking the first drive with the full setup using the ST204 cylinder and booster

I don't think the new bias will be very evident. And if anything, it will be an improvement. That's just my ignorant presumption

If you are concerned with it, you can just install and Bias Controller and be done with the issue. Or change bias with using pads with different grip characteristics

As for your question about using the ST205 master cylinder, I know that people have been fine using the ST204 cylinder.

A larger master cylinder may not be necessary and probably wont help with the bias.

There are so many factors involved in brake bias and also reservoir volume and pressure. Ill break my fingers going on a rant so here is a thread thatll learn ya some things haha. The thread kind of tumbles into a volume and pressure math-off, but for the upgrade that he has gone to from stock is a bit greater than gt to gt4 brakes.

Unfortunately is raises alot of questions and makes everything a bit more complicated

EDIT:
looking back on this I am going to revisit some of this information after I'm off of work. I'm a little scatter brained with my posts when I am at work haha
