    Do you mean for WRC? Yes, I agree with you on that. Brake technology on WRC cars is much more advanced to their road-going counterparts.

    Yessir, they do. I've for pictures around on here, in various threads, with 15" Braids on the stock brakes.

    ^^^^^Good golly, I wish I had money coming out my wazoo, I'd have that $11k brake kit & a few STis to install them on in a heartbeat.

    The caliper seems to be roughly the same size as the stock one. it would have been a good upgrade to do the pads lines and fluid too but as i stated before this mod had an obvious aesthetic motive behind it.

The new 2-pot caliper has a similar pad area compared to the outgoing 4-pot brakes as well as a similar brake disk diameter. The 4 pistons should slightly improve the brake-fade resistance, but you will likely not notice unless tracking the car. Even still, the 4/2s look MUCH better. Let me put it this way: my MS3 with 1-pot calipers at all 4 corners stops as well as my WRX with a 4-piston BBK up front since the pad area is similar.

    Why did you do all that work and not replace the brake lines with SS lines?? That's a HUGE improvement in brake feel.
    As I stated in my first post I can not say for sure that all the credit from the brake feel could be attributed to the new calipers due to the pads and fluid. Why not SS lines? I am going to do those and the GS master cylinder brace next. I wanted to see where this put me as far as pedal feel. I can put those on and bleed the brakes in an hour or better.

    they were saying: "WE WANT TO TAKE OUR CLOTHES OFF AND ROLL AROUND IN A POOL OF JELLO FOR YOU BECAUSE OF THOSE SEXY BRAKES! THEY LOOK SO MUCH BETTER THAN BREMBOS!!''

    thanks guys for all the positive responses and the good information.

    I forgot about the jello part... hope that doesn't put anyone off from doing this upgrade.

    Yeah. Because disgarmented women in jello would tend to do that.

    I upgraded to 4pots on my 2.0R(euro spec. NA) a few years back before I got my '08 WRX and it did improve the way it felt when breaking. (4 pots should give better control and better heat distribution than 2 pots) Later on I bought braided hoses and Super Blue brake fluid but didn't feel any difference. I had Bluestuff pads and DBA4000 rotors mounted. I think it might have given me something on a trackday where the fluid gets warm and the rubber lines get more "spongy". I would definately buy pads and rotors first.

    If and when I upgrade the rotors the ss lines will be done as well. The pedal feels great now.

    Guys. Let's keep this to a DIY thread. If you want to discuss other series of calipers or talk about how it was a waste of money or time please start your own thread. I didn't take the hour to write this up and stop my install to take pictures so that people could come on here and babble about other brake systems. Pm me if you want to chat. Respect my work
