Brake pads R1 Concepts or STOPTECH

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.

I havent had an issue with them in 2 years.

I used the R1 concepts drilled and slotted kit with pads. Front and rear total was like 500 bucks. Did it myself. They work great.

They seem good so far. I'm not very handy and I was able to put them on pretty easily.

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.

I ran r1 concepts ceramic pads and rotors on my mk6 and they were awesome for all 4 for under $450 with a 20% off coupon on their website

New rotors and pads without breaking in at all, just normal driving as soon as changed. Pads lasted 30.000km ish, while rotors wrapped at about 40.000km ish (pads replaced at 30k with same R1 concepts). Brake feel and performance was OK, but much worse than when broken in. Light squeal at about 15.000km and onwards. New rotors and pads following break in procedure, 10 stops from 90km/h (55mph aprox), never coming to a complete stop, then driving 30 minutes never coming to a complete stop, rolling to a stop on neutral and waiting another 30 minutes. Pads lasted about 40.000km ish, rotors lasted 80.000km ish, pads replaced at 40.000km with same R1 concepts ceramic.

I installed Stop Techs in my 2016 WRX at around 10,000kms. Didn't notice much difference. Hated them, squeked a bit when new. But they left brown dust on my nice clean gold rims and I hated that. Swapped the stockers back in and again didn't notice much difference in stopping, maybe i had to push slightly more to come to a stop. But so glad I don't have shit coloured brown front rims.
