I have always done pads and brake lines on all my cars at the same time, so I don't have a good handle on how much the better brake pedal feel is attributed to the brake lines over the pads. But physically, it always just made sense to me that a plain rubber hose would expand more under pressure than a rubber hose encased in a steel mesh. Would it make much of a difference in auto-x? Probably not. But when I'm going triple digit speeds down the front straight on a road course, down hill, towards a hairpin (thinking of turn 2 at Hallett), I would like my entire braking system up to snuff. I bought RBF660 fluid, SS lines, and CarboTech HP10 pads for my FR-S when it had less than 4k miles on it because of this.

Regardless, I was mainly venting because now do I not only have to change pads and rotors when I go to a track day, I also have to change brake lines. But it's fine, I'm still looking forward to competing in CS.
