Brake pads STOPTECH or Project Mu
Higher-temp and higher-mu pads (Project Mu HC+R3) + braided brake lines + DOT 4 fluid for me. Slotted fronts, blank rears.
I have stoptech "performance brake pads" on my front and rear. Feels like OEM but more dusty
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.
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.
Red stuff are absolutely NOT track worthy. Will fade in like 1 lap. Any pads advertised as "low dust" tend to fade pretty fast. Yellow might be ok but I think they're still more of a performance street pad. Project MU HC+ are a good streetable track pad, maybe the best, use them on my Megane RS, no trouble with 20 mins sessions on high speed tracks and trackday tyres (Yokohama AD09). A little squeel at low speed on track but quiet enough to live with IMO.
There was a noticable increase in stopping power, but it came with a significant increase in brake dust. They also started squealing recently. I recently checked the pad life and it's been okay. So far I've put 10k on em, and I'm estimating that 1/3 to 1/2 of their life has been used
I used Stoptech sport pads and am kind of regretting it. They don't seem to have great initial bite so I may swap to something else this summer.
