I track mine and street drive them as well. My don't really squeal on the street. I think it's because I added a set of these during the install.blueline wrote: Sat May 30, 2026 7:29 pm
Be prepared for them to squeal for the last 10-20 feet of a street driving stop - mine do anyway. The squeal is often absent fresh off the track if I've been able to burnish them a bit, but street use stopping will wear off much of the pad material resulting in a bit of squeal in slow, traffic laden stop and go conditions. (They don't squeal at all on track and they don't utter a peep under full, heavy braking.)
Intriguing. Did you perchance have any squealing prior to using these shields or have you used them from the start with your Ferodo pads? I noticed that the shields are marketed as a heat-reducing add-on (always a good thing) and am guessing the squeal reduction is an unexpected bonus.marin wrote: Fri Jun 12, 2026 9:40 amI track mine and street drive them as well.

Also kind of act like anti-squeal plates / brake shims.

My squeal isn't that bad at all and, as I mentioned before, is only at the very end of street stops. It's from the front rotors only best I can tell.
There's nary a peep on track or even when pulling in the pits to a slow stop. I believe that's likely due to having redeposited a good burnish with proper and hard track braking. Plus, the rotors are extremely hot. However, that complete lack of squeal will go away after a dozen or so regular street stops. I'm not wild about the noise but I've learned how to navigate street stops mostly squeal-free via PDK downshifts and judicious, light touch brake pedal play.
