I have also been wondering about the bias. I have HPS's on the back. Of course there is a lot of pad left back there. The fronts still have 1/4 in, not sure they will stand a full track day but the backs definitely will.

What can I expect if I went with the HT-10's on the front and left the HPS's on the back? Some guys match up all four corners with the same pad and some don't for whatever reason. Any thoughts?

I do a lot of work on my cars myself but really hate thinking about what and how to do things. I really hate paying people to do things I can do myself. The thing is I would much rather just drive.

You go on those mustang forums and there are so many differing perspectives.
