The pads make a big difference, not as much as SS lines but they do provide quite a bit more bite. I bought the middle of the line Galfer pads and SS line from Pashnit. I forget the part number for the pads (1375 I think) but they are the ones Tim described to me as upgraded from stock and are considered canyon carvers. I wanted to see how much each step helped me so I rode with just the new lines for 2 weeks before putting the upgraded pads on. I was shocked on how much the pads increased my stopping power, I thought the lines would do most of the work and the pads would add just a tiny bit more but I was wrong. Again, the SS lines added more stopping power than upgrading the pads but the pads sure helped too. I am still running the stock rotors, I wanted to upgrade them too but Im a cheap bastard and wanted to see how much better lines and pads would do before I dropped anymore coin. For the type of riding I do my current setup will be just fine so I plan on using that money for a better seat.
