Can you clarify regarding the DCT30's? You melted them on the track? I'm not familiar with R12's, who makes them?

R12 is made by gloc. DTC 30 i essentially melted. I got them too hot and they separated from the backing plate and crumbled. They are not made for heavy track cars, probably fine on the street though |

I think what he means is that the same pad should not be used for street driving, and tracking with slicks. Which, I’m in agreement with, a pad that is acceptable for good street use really shouldn’t be used with a slick as its not going to have nearly enough stopping power for slicks.

R12 is G-loc's third step up in their track-rated pad ladder, and it's essentially the same pad as Carbotech's XP12. FWIW, I'm not the only one finding that 10's last slightly/somewhat longer than 12's. As long as you aren't needing the extra temperature capability of the 12's, anyway.
What makes me uneasy about Hawk's DTC30/Street Race compound is that mu falls off a cliff at just over 1200°F / 650°C. I'm afraid that without quite a bit more experience you might not feel them going away on you in time. I'm not at all sure that I would. I do trust at least the general shape of Hawk's or any other pad mfr's curves without worrying if the "exact" temperature at any given value of mu for any given batch is precisely as plotted or within some unknown plus/minus amount . . . I think I'd trust mu to be within ±0.02 before trusting °F/°C to be within 25°. Norm

What group do you run in? How much seat time do you have? Number of track days?

BTW I've used Pirelli DH take offs and and only got 3 sessions on them. After that I was off by a second. They are not cheaper in the end then new Hoosiers in my case.

I have indeed run the stock pads with a few different tire combinations including SC3R's, NTO1's, Hoosier R7's, and DH take-offs. They worked for all the tires. With that said, they WILL fade. But it is a very linear, consistent and manageable fade. I never felt they truly impacted safety or lap times. You can run them all day and they won't destroy your calipers either.
I finally ran a set of DTC70/60's this past event and I really did not feel a huge improvement. They generated a few hundred degrees more (I have temp stickers on calipers), which in turn caused some fluid issue. They also after one event turned all four calipers into Brownbo's. All in all, taking into account the extra heat, "destruction" of the calipers and marginal improvement in braking performance, I can not say I find them worth it. I will be giving them another go in two weeks at a different track, so we will see if my opinion changes.

I run 70s and smoked a caliper. RB pistons now with DBA rings and they feel spectacular! |

Are those pistons available for the ZL1 calipers? Do they get rid of the rubber boots entirely?
