Brake pads Carbotech or STOPTECH

I’ve used carbotech XP10 for years because it’s the only pad that has never had any of these kinds of problems. Also also swapped between 1521 and XP10 seamlessly. The only time I had a problem like this was when I used some very cheap rotors that couldn’t handle the track abuse, you could actually see the rotor surface getting pitted. Yours look fine by comparison.

For my GR86 Carbotech XP10s have been amazing on the track, seriously no complaints at all. The XP10s with Castrol SRF have been a great combo and held up really well even on some really big/high speed tracks. I swap in my OEM pads when I’m not tracking the car for awhile. It’s not great because I have to bed the pads every time I change them. Once I’m through the OEM pads I’m going to get the Carbotech 1521’s for the street, that way like you mentioned I think I can avoid having to avoid bedding my brakes with every change. The XP10’s function well on the street but they feel a little rough if not up to temp and they are insanely loud.

I personally use Carbotech XP10 for track and Stoptech Sport pads for street on the same rotors

I went to Stoptech Street pads at 35k miles on the fronts only, took care of the issue after a few bed-in runs. Still no shudder at 75k and original rotors

I had Carbotech XP12 before and they're were great, but squealed like a pig on the street. I haven't tracked the Dynamic Friction but aggressive street even on V730 & daily driving, they've been great.

Grimmspeed MCB, STOPTECH Sport package (pads, rotors, lines) and the GR86 Shock/Strut retrofit.

I use Carbotech xp10 in the front, xp8 in the rears. Love them. Semi heavy car but they feel great the entire weekend. They are very loud on street though

I went from EBC to Carbotech. It’s a night and day difference. I’m running XP8, but my car is very light.

I run carbotech xp8 on the front of my c5. Still a group 2 level driver. They’re a good pad for a car that’s driven to the track and home, but dirty and noisy at times for a street pad. They’re considered entry level track pads. I chew up rotors but don’t get fade, but my local tracks aren’t particularly hard on brakes

I tried the carbotech 1521 to try to get silent street pads with better bite but no dice, it’s the same as the OEM akebonos
