Thanks all...looks like Craig has a set that will get me through it. Good to know on the Carbotech and Cobalt pads...will probably order a set and give them a shot. The GLOCS/Carbotech have been my favorite so far because they are so easy to modulate...makes braking easier for a hack like me.

Used to run carbotechs, cobalts are the shit, you won’t be disappointed, thanks Jerry!Originally Posted by drecords

What would be a good cobalt replacement for the XP/GS 10s?
If anyone has some used ones for the stoptechs i'd like to try them out some time.
Just a public service reminder from your nerdy NASA engineer: Many of these different race pad compounds leave a deposit of material on the rotor. The pads often won't even work well until they have been pushed hard enough and heated up enough to leave this deposit. It's not uncommon for different pad materials to not be compatible with each other. Swapping different compounds around can lead to some really crappy braking.
I bought my Stoptech's used. Whatever pads were used before I got them most certainly were not compatible with the Porterfield R4 pads that I use. As the different deposits unevenly wore off/mixed/deposited, I got brake shudder that bounced the steering wheel out of my hands under heavy braking. Turning or replacing the rotors is the only solution. Turning slotted or drilled floating rotors is logistically challenging...

Yeah I'm familiar with the concept of pad deposits on rotors, but I figured my XP10s were abrasive enough to make quick work of whatever my used stoptechs had on them.
I do wire brush the rotors before installing different compounds with some brakleen liberally sprayed while wire brushing. Usually get some slight pad judder when they're bedding in but it goes away afer a few good stops.

Just following up, my g loc 10s are almost done and curious about the cobalt xr2s.
Anyone done a comparison between these compounds and have a half worn set I can bum off them to try?
I have at least two sets with 1/8" to 3/16" left on them. You are welcome to them at COTA or even before that if you want to try them.

Your issue Richard is the R4 is not a very aggressive pad and has trouble removing the old transfer layer.
