Galfer greens

Is anyone using the Galfer green brake pads? If so, how do you like them? Here's the part number: Green 1532: GG-rated compound. I mostly do street riding, twisties on the weekends, and one or two track days in a year.

I have em up front they seem to work better than stock but they warped my rotrs a little you cant notice it when using them in twistys or high speed but coming to stop you can feel they're warped , time for wave rotors
