I'm not sure about the performance model 3 and it's brake pads but you can get performance break pads that sound like that. Even ones that sqeak at low speed.

I'm not sure about the performance model 3 and it's brake pads but you can get performance break pads that sound like that. Even ones that sqeak at low speed. Ferodo DS2500 if you want a set for yourself. Drive to the track, track and home again without issues.

I just checked: https://youtu.be/-KNXvqmqNr0?t=30 https://youtu.be/-KNXvqmqNr0?t=30 To be honest, what I hear is a whistling sound, not metal on metal – that kind of sound that instantly sends shivers down your spine.

That's because they're doing the same things to the rotor at low temperatures that a caliper does - just abrading away rotor material to slow the car. Track pads are great when hot, not so amazing when cold. Yes, I know there are plenty that claim to be able to do everything, but your rotor life will suffer. However, it's not something one should expect from a factory vehicle - and if you've installed higher performance track pads yourself, you should be able to determine if it's normal. Also, they'll sound the same from all four corners - this sound just came from one corner.

I ran DS2500s for years on my first STI. They would resonate and make a squeal, but it wasn't at all the same as metal-on-metal grinding from a worn out or missing brake pad. Also, I don't recommend DS2500s on a street car. They're intended to be a compromise pad that works on the street and the track both, but the performance is significantly worse when they're not heated up, so the first stop of the day on a cool morning can be surprising. Better to get real street pads and real track pads and swap them. It's super easy on fixed caliper brakes.

  I ran the DS2500s for a couple years before shopping around a bit to see what was out there. I settled on custom made pads using a Mintex material which pn escapes me now. I used some pretty decent brands and pads and found the Forodos were the only ones that I couldn't get to fade in the hills. Their friction coefficient starts at 50c so it's definitely not unreasonable like actual race pads that can start in the 125c+ range. I only ever found them a little suprising when they had been hot hot and then the next morning it would take a bit more of a press on the peddal to pull up and the stop lights. I still always had confidence that if I stood on it they would pull up in time. As for running propper race pads at the track, that's fine and I had the same brembos you would've but replacing the rotors I was using wasn't something I wanted to shell out for every few track days. The Forodos never had any fade issues on track and I have a picture with the back wheels almost lifting as I brake from speed cut.

> I'm not sure about the performance model 3 and it's brake pads but you can get performance break pads that sound like that. Even ones that sqeak at low speed. No. If you don't know anything about cars please feel free not to comment. Performance brakes can absolutely be noisy but they ABSOLUTELY do not sound like metal scraping metal. I have heard all kinds of performance brakes - carbon brakes, high end drilled rotors with the hardest pads you can imagine, everything. The most alarming sound you'll hear from performance brakes is a nasty squeal. They DO NOT sound like this. You are spreading misinformation.

  I used to get custom made pads for my car that I would drive on the street and track. So yea thanks for your concern. Sintered metal pads definitely sound like metal metal contact at low speed and even more so when they've recently been hot. Watch the video. It doesn't sound that bad and I can understand the engineers but probably wouldn't expect that much from a "performance model" Remember my BMW Martin, that ran pads that would make horrible sounds. However the Integra and it's brembos that used to take a beating a Ruapuna often sounded like something you would want to pull over and check out. ;)
