cobalt brake pads
im rethinking my z06 brake decision and contemplating possibly trying some different pads with the z51 brakes. my issue is brake judder. Ive had the same problems with the stock pads and with carbotech xp12. Ive been told by some that carbotech pads are notorious for judder. I'm thinking of trying a couple sets of different pads with the stock calipers specifically g-lock and cobalt. Looking for a little input from those that have been down this road. Every time i try a new set of pads it's cut the rotors and spend big bucks for pads. sometimes I think it might be best to just buy the Essex stuff and be done with it.

XR1 worked well for me, but had a pretty short life. Did you try EBC SR11s? That might work better for you with longer life.
You don't need to turn your rotors every time. Race pads do a pretty good job on cleaning up the rotors, especially when cold. Just use them for a while until vibrations disappear.. or it would already happen by a session or two during a track event : )

Carbotechs are very sensitive to transfer layer and the bedding process. It's been about 10 years since I used them but I would always have a set of rotors that had seen nothing but carbotech since new. If I wanted to swap to street pads I also swapped rotors.
As a data point, I ran hawk DTC60 this year and also had a lot of judder on my Z51. Z51 rotors are cheap from rock auto so for whatever pad you try next, I would also start with fresh rotors

I’m running XR1 Cobalt pads and like them a lot. I find they last more than twice as long as the G Loc R12’s I was using, and I don’t get any shudder. The G Locs would shudder like crazy after the first session each day. Using stock Z51 rotors and calipers.
