something else to add, I did the Z1 base brake upgrade with stainless steel lines, slotted rotors, and stoptech pads. So far I love them for what they are. I needed new brakes and couldn't do the akebono upgrade so I figured this was a good inbetween. They pedal feel is night and day with the S/S lines which were a bitch to beed afterwards but something I'm glad I did. The initial bite is alittle better but they are slotted and not drilled. I will come back with a better review when I take it in the canyons.
