Powerstop Track Day pads

Got a chance to try out the Powerstop Track Day pads on my e90 m3 this weekend at Nelson Ledges hpde. Wasn't expecting too much for <$100/axle but they did alright. Longest session was about 40 minutes and the course isn't particularly hard on brakes, but they held up great, felt fine and didn't fall off one bit running sub 1:20 laps on re71r.

Hoping they do as well at mid Ohio in another month, will report back then.

Even bedded they were miserably loud on the street at first, but they've since quieted down and are fine for daily use. Can't tell how dust is since there's so much asphalt and rubber on the wheels.

First impression is good, especially for the money.

How bad were these on the street? Anyone else have feedback for street use? I don’t want to swap pads every track day.

They will stop just fine on the street. I'm on my 2nd set, and the first set were pretty quiet all around, this 2nd set is much noisier. I haven't tried any backing plate spray or gunk or other tricks, but currently I've got pretty annoying squealing between maybe 10-70% of braking force?

Squealing is typical for a race pad. Re-bedding will help stop the squealing, but it will return within a day or two. This is the trade-off with a race pad.

Anti-squeal compound won't do anything.

That's how high heat brakes are. The squeal is from the pad and the rotor. So all that grease/spray/etc isn't going to help.
