Excellent - glad you've found an improvement. It doesn't take much to improve the brakes, does it?

The braided lines when you get them will make the pedal feel firmer since the lines will flex a lot less than the factory rubber lines. If you want to firm it up even more, then consider a Master Brake Cylinder Brace to support the MBC and prevent the firewall from flexing when you mash the pedal, and don't forget my aforementioned suggestion of optionally replacing the factory MBC altogether with an STi version too.
I was going to procrastinate, but I put it off...
