I've even resorted to a dab of Sonax break dust cleaner on the disc to dissolve some of the pad surface to get some temporary peace.

They are fantastic stoppers(even the street "10" pads) on the track, but the "30's" are so hard they spark like a Disney fireworks show when bedding.
The metal brake dust turns to invisible rust and will take off powdercoat on rims if left on to long.
The "30" will wear out discs quickly, in as soon as 4 or 5 track days, but I was using them to outbrake the faster cars (Vettes etc.), on the straights.
My worn out discs were not gouged, but worn smooth and evenly.

Has ANYONE found quiet pads from other than Willwood or R+R that are quiet?
Ive tried 3 different street pads and nothing helps. Ive pretty much parked the car aside from track days. They are coming off. Ill stick the stock stuff back on until i decide what setup to replace them with.

BP20's. PF R4S. And one other I can't remember.

I put my stock brakes on yesterday with the same r4s pad and its so much nicer to drive without the noise.

I will probably eventually just pull the BP10's that I have and run some organic pads on the street then swap them for autocross or for track days. I don't do enough racing to justify leaving the BP10's on, and I doubt I will need them for aggressive canyon drives. I have been considering some ceramic pads too. I figure the larger size has something to do with the noise, but it is probably mostly due to semi-metallic compounds on the street/track hybrid pads.

imo, its not the pad compound or the size. Ive ran these r4s pads on many other cars with zero noise, ever! Ive ran them on cayenne brembos on my gti that had a significantly larger pad size as well. I think its more related to the caliper structure? Lack of dampening maybe?

Porsche felt it necessary to educate owners with this video, and they say size is a contributing factor:

These are Superlight calipers so maybe that matters.

Good video, I still stand by my comments.

In my experience the larger pads many times have weights attached. I expect this helps with vibrations/noise. So yes pad design/size play a factor. But a properly designed caliper and pad setup shouldnt have nearly the noise this wilwood setup has regardless of size.

Do you know if the other kits have noise too like the OEM Brembos on the performance package, STI Brembos, Stoptechs, or AP Racing?

I don't have first hand experience with those kits on these cars but i expect any of the oem kits to be quiet with street pads. Ive used other oem upgraded/swapped factory calipers on other brands with no issues. Ive been around many different factory brembo cars with no issues.

CSG says the street pads on their brembo kit are quiet. So I'm either going with their kit or AP.

Loosening the e-brake helped the rear heat issue significantly. They run only slightly hotter than the fronts now, if at all.

Brakes feel good, and I'm not having issues with noise except during the occasional hard stop.

I've got the AP/Cosworth 350mm kit on my 86. It's quiet as a mouse utilising a caliper designed to be quiet and street friendly.

This past month Iíve been daily driving 2-3x farther per week and carving through my mountain much less (only a few times this month compared to 3-5x/wk normally) and now I hear squeelling once or twice a day.

Iím on BP10ís. Normally when I start hearing the rare squeal I know I need to bed them in again or just do a mountain run with some aggressive braking. Takes care of it for a while. I didnít buy a bbk for daily driving reasons. And I would hate for unsprung weight to be added to just help with some squeal.

Huge sprung weight savings from the superlightweight caliper option is worth it !
(I'm old and losin my hi frequency hearing daily LOL !)

Does anybody have any options on the solid rotors versus two piece rotors in terms of sound? I didn’t know if the aluminum center resonated differently.
