I have a KSport in my car and I love it.
Basically bent the existing hardlines up to it, interputing the line that goes to the rear brakes.
One thing that I have noticed is that no matter how well you bleed it or how well you install it you NEED very aggressive rear pads. I have Carbotech rear pads and it takes 1 finger to lock up 17x10's in the rear. If you run shitty pads you will have a huge problem with the effectiveness of the mod. Also the bolt on lines don't give the same feel as the shorter method I used. They also make it a bitch to bleed.
Also the "parking" feature is worthless, so my race car has no parking brake. If it was a DD I would probably keep the stock one and add this.
