Brake pads STOPTECH or OEM Toyota

It's a solid pedal feel.

To me it looks like brake pad material on your rotors due to your street pads melting. Slap a new set a cheap pads on there from Autozone or something and drive it for a week or two that material should come off. As long as you don’t have vibration while braking they should still be good. Just make sure to use track pads next time. I personally run StopTech 309 pads because they’re good on track and street

I got Stoptech Sport pads that I've used on track and street for many years.

I run StopTech Sport pads on my E92 M3 and they hold up very well for a dual duty pad. I prefer them over the other options listed.

Brake pads - $90 for parts

I had this symptom as well 2 months ago because my brake pads were worn out. The rotors was fine so only had to replace the brake pad and the braking vibrations went as well.

DIYer advice: buy Toyota pads/rotors from your local dealership's parts counter. Take a photo of your VIN for the parts guy. Once you're in their system, buying parts will be easy. You'll typically pay 20%-25% more for OEM parts, but do you really want to buy cheap pads/rotors?

The StopTechs Sports are the better track and street option, I used the front pads in my E46 M3 for 10k+ street miles and a few trackdays. They have good feel and modulation. Just had a little bit of fade towards the end of a 25 minute session.

The only difference I noticed with Stoptech is more dust.

However, on Toyotas, I always pay the extra money for genuine Toyota discs and pads. They’re still made in Japan or the US. Whereas all of the aftermarket options for Toyotas are Chinese-made junk. And since those aftermarket ones wear out so fast, they end up being the more expensive option per mile vs the genuine parts.
