Which ceramic pads?

[Norm Peterson]

Are the slotted and drilled pad and rotor sets on rock auto any good?

Not a fan of drilled for any use other than for a mostly trailered car show build.

Slotted can offer slight improvements in certain wet driving situations, and will give little pieces of road grit better places to end up in than being trapped between the pads and rotors, where they tend to score the rotors and make noise.

Kinda like Oreilley rotors on my f350... out of round on 9 months. You get what you pay for.

This is partly why I didn't respond to initial questions specifically mentioning mass-market ceramic pads. My experience-based opinion regarding that level of brake pad is not very high at all and I'd rather not start somebody else's thread out with harsh-sounding criticism for his proposed choice. I'll let the thread develop a bit before stepping in.

Powerstop Z26

Powerstop Z26 pads paired with Raybestos slotted rotors here. All is good.

My primary objective is to eliminate brake dust.

Then the Z26's are fine.

I don't mind drilled rotors on a street car especially if they are reverse cooled.

Thanks for the help. That's sounds like a good solution.

I guess no one here answers brake questions. I asked one with no response either.

Not sure about mustangs but I run ceramic pads on a 2002 F350 7.3 and also my much later model f250. I prefer the performance especially when towing.

You prefer the performance of ceramic pads over semi-metallic pads? Interesting.

I'm assuming this is for street use, yes?
I have more input for race pads but I hear G-Loc GS1 pads are great for the street

I believe those are semi-metallic and not ceramic.

Ok, good catch.
I don't pay attention to what they're made of anymore. As long as they work well

I have my doubts regarding that.

Certainly from the standpoints of noise, dust, and rotor wear rates the GS-1 and Carbotech's 1521/Bobcat pads don't come with the traditional downsides of semi-metallics. The Carbotechs might be just a tad better with respect to dusting.

I've used them, they do work well and don't dust a whole lot. You can overheat them on the street if you get too frisky though. Ask me how I know lol.

Yeah you can glaze the GS1s with hard driving, but IDK if that qualifies as “street” use. They’re pretty decent street pads, dust less than the stock pads but IMHO can take a bit less hard abuse (i.e. repeated very hard stops or small track use) than the stock Brembo pads before they glaze. I’ve used them for tons of autox and some light track use and like em fine, but cook em too much and you’re better off with dusty pads designed for track.

Powerstop pads and rotors on mine.no issues.

100% agree with all that. You'd have to be driving pretty recklessly at least on the street to glaze them. I'm currently using the Raybestos street perf semi-metallic pads (same temp threshold as the R8) and I've been happy with them so far. They're pretty quiet and stop well but they do dust a lot. My only problem with the GLOC GS-1 is they made noise on my car and I have to chalk that up to the fact that they do not come with backing plates on them. I did everything to eliminate it, re-installed them 3x, even had my mechanic check them out. It was fine they just make noise.
