15 sessions of aggressive autox doesn't quiet them. 20min sessions at MidO doesnt quiet them. Not sure what else there is.

If your car is not being driven in a race, then take the racecar pads off of it.

Street pads man. Problem solved.

As I mentioned, Ive had Porterfield R4-S pads on it and BP20's. The R4S pads Ive used on 3 other cars with a total of 5 brake setups and they never made noise. They are terribly noisy with this Wilwood setup. The same with the BP20's I have 2 friends with them on small wilwood setups and they are fine.

I believe its something with the calipers not having any dampening springs to hold the pad from vibrating. They screech like a Pterodactyl whether they are cold, warm or smoking hot.

Different brake kits most likely require need different configurations. So why spend thousands on calipers but gripe about putting street hardware in while driving on the street? A set of street pads costs less than a single tire. Would you think it kind of silly if someone was complaining about their 200TW tires not being quiet and comfortable on the street? Get the right pads for your driving conditions.

I've got the stage 2 kit with BP20 pads. I don't think this combination will ever be 100% silent on the street, but after a good bedding (track weekend), it definitely quiets down. Under light braking, it's silent. In moderate braking or once the brakes get some heat, it will still screech a fair amount.

Once the rotors lose that transfer layer, it's usually back to screeching full time. I don't mind since my car is driven mostly on track, but friends/family who ride in my car usually ask whether I need to change my pads lol.

@cruizin01 Unfortunately I think you're right.... with this BBK using the super-light Wilwood calipers, they just reverberate alot of pad noise. The BP10s that came with my performance kit sequel pretty bad, tried some hawk hps and they actually after breaking in turned out to be even louder....

I even tried using that orange brake noise grease on the back of the pads, that helped for about a day. Maybe there are some magical shims that would help these out, but not sure.

The only way I managed to quiet down my kit was running EBC greenstuff with their anti squeal tape and placing the wilwood shims on top of the tape. and it wasn't 100% quiet.

I've ended up returning to OEM calipers, which surprisingly improved my lap times by 1.7 seconds.

I have stage 2 front caliper with Ferodo DS2500 and blank dba 4000 rotors. Brakes are silent when cold (i mean, dead cold) and they start to squeal when they get warm after 3-4 stops.

I dont follow your logic. Having a setup thats capable of withstanding more heat shouldn't automatically force you into a setup thats miserable on the street. Hence why I attempted a couple different sets of street pads for street use. Ive had setups on cars with significantly larger calipers than these wilwoods with zero issues using the same pads. So its nothing to do with how much I spent or these calipers being too "racecar".

I understand. Sometimes that seems to work and other times it doesn't. Last autoX event coming home they were even more noisy than when I left the house.

Yeah Ive tried the orange goo. Ive tried chamfering the pads. Ive tried the magic sauce that you soak into the pads to quiet them down. Ive tried a seperate set of rotors. It all is very temporary.

Im definitely considering that. At this point Im only doing 1-2 track days a year and several autox events. Beyond that its just a weekend/fun street car. The stock setup would be fine with the right pad setup.

Yeah, same here. They are quiet until warmed up.

Thanks everyone for your input.

I haven't tried many setups with my sport kit but the only pads I've found so far completely silent were EBC Yellowstuff. Don't need to run any grease or shims or anything. BP10s were mostly quiet with just the occasional squeak. Winmax W5 are quiet when dead cold but make terrible noise within about 3 or 4 stops.

With brakes, more heat capacity almost always means more noise when cold.

The problem you're running into is that you expect a cougar to behave like a Scottish fold without understanding the effort it might take to figure out what will make it more civilized.

Different materials, design and construction create different harmonics under different pressures and temperatures. Brake calipers, pistons, pads, shims, fluid etc are designed as a system to operate with degrees of performance (heat capacity, noise, vibration, longevity, etc.) given a specific performance and comfort goals. An OEM brake system is designed to produce street driving condition performance and comfort. Most aftermarket Big Brake Kits are not designed to produce those same results but can get you close to that with some pad tuning effort.

Undoubtedly some additional research on pads was needed for this kit if you intend it for a street car . Note that most of the marketing materials on the kit don't mention it being for that purpose. Managing expectations matters. Put racecar stuff on your street car and watch as it magically stops acting like a street car. Or, continue working to find out which pads might be totally silent on this kit. I think @Lynxis posted just above that EBC Yellowstuff seems to do the trick. Try them.

@DAEMANO alludes to this but one of the major factors here is that Wilwood and other dedicated racing calipers don't have any harmonic dampening built in whereas any street focused caliper will. For reference, several people reported the Winmax W5s as being civilised enough for street use on an OEM caliper but in the RR SP kit, they are far too obnoxious for that.

So far, Yellowstuff is the only pad I've found that stands up to track abuse and is still quiet on the street in my SP kit. I do have complaints about them in that they don't last very long and they don't have the type of bite I'd like from a track pad but they are certainly serviceable for their purpose as a dual duty pad. I'm going to try the bluestuff down the road but not until after I've been through the other pads I've got.
