Watching vids from Sebring and AMP just now it did it almost all the time at AMP, but that's a lot of gentle braking to get weight back up front, but even under heavy braking it seemed to do it there. I had just switched from S100s to C300s with no extra bed in there though. At Sebring after a full bed in on the street from 70-5 until they were smoking a lot, repeatedly they were much quieter and mostly just made noise on application/release and light pressure. Vids are on youtube if you want to compare noise to yours. daveror channel.

Alright, I'm going to be abusing the S*** out of them this weekend to try to quiet them down

On the other hand, while they work just fine on the street in terms of stopping, the noise is... atrocious. Deafeningly loud at street stop speeds. Street pads are on the way :p

Oh on the street they are a NIGHTMARE lol

Luckily I bought S100s at the same time. The S100s make noise also, but I'm not sure if it's by design (maybe all the AP performance pads make some noise) or if it just can scrub off all the C300 compound though

They are livable at least, the C300s simply aren't usable on the street beyond driving to the track and back home.

I'm driving the BRZ to and from work this week where many trucks traverse. It's pretty funny how I get them looking like some train is about to crash into them. Then you hear the squeaking as I'm trying to pulse the braking so it's not one sustained scream. I love traffic too.

I'll edit the first post later today to ensure we have a nice template for everyone to apply, that is if nobody complains about the template.

I had Carbotech XP10/XP8 combo on my 350Z and loved them on the track. On the street they were dusty and squeeled like a pig. But apparently the dust is safe for all wheel types (which I can attest to as I left my Volks (aluminum barrel) with brake dust on for a few months).

[ATL BRZ]

Brake Pad Manufacturer (F/R): Stoptech street performance
Caliper (F/R): OEM
Rotor Size (F/R - IE OEM or specify): OEM
Compound (F/R): street/autox/track
Tires: 235/35/18 BF Goodrich GForce T/A

Feedback:
First track day was with Stoptech Street performance pads front and rear. The pads were nice to my OEM rotors, they transferred somewhat evenly and they took a decent pounding after bedding properly. Also had OEM fluid in the car and I don't think I boiled it. Probably came close, but with the right amount of modulation and trail braking into corners I managed to keep everything under control temp wise.

Also they seem to be wearing well. I can't see the pad backing plate through the inspection hole yet, but it wasn't that much track time at 7 or 8 tenths driving.

Scores:
Dusting (1=high-10=low): 5
Cold bite (1=low-10=high): 10
Hot bite (1=low-10=high): 7
Modulation (1=low-10=high): 7
Noise (1=extremely loud-10=quiet): 10
Pad Lifespan (1=short-10=long): (estimate/actual) not sure probably 4/5 if I track them a lot
Does the brake dust with this combination damage the wheels/paint if not cleaned immediately? (Y/N) No
Brake ducts: (Y/N) No

OT: did you run video at AMP? Uploaded anywhere?

First post has been updated!

GO!

Even the Carbotech RP2 (another enduro compound) doesn't do that...

Mike, I've got to ask about your bedding claims about eliminating noise.

I have Carbotech XP10s, XP8s, and RP2s and they all make crazy loud screeching noise! And I had them pre-bedded by Carbotech themselves to save me the hassle at the track and not waste any time.

So I disagree I guess?

My XP8s are 100% silent, XP10s were silent except at the very last few MPH before stopping. They've always been pretty quiet for me, weird that you had issues with them I never used the RP2s though.

They sound like a subway train coming to a stop when I'm just lightly braking that last few mph on the street. Like crawling up to a stop sign or pulling into your garage.

When hot and on the track they're 100% silent. I'm just talking about street driving when they're (mostly) cold. Mike says they're suitable for street driving because they're quiet but when on my car they're loud enough to scare the crap out of inattentive pedestrians. I literally made a girl jump into the air once (accidentally) when she heard my brakes squealing.

You should hear my AP C300s... actually you can in the track video thread.

I drove the XP10/XP8 combo on the street for about 5,000 miles. Did you have some other track pads on the same rotors previously? Just trying to figure out any differences.

That just means that the pads have been heated up to the proper temp. It doesn't mean that you have a proper transfer layer.

Personally, I've never bought the pre-bedded pads, and I don't recommend it to anyone either; you can bed them in fine at the track, and unlike some other pads, you certainly won't lose a session bedding them in.
