For Street:
For Track:
My main issue with the pad is that track use is still glazing my rotors a bit. After a hard track day, I get vibrations on the highway while braking. This usually goes away in a month or two of street driving, but it's a bit annoying. I'll probably go a step up and try the ME20 next and see how that compares. I'm basically trying to find the least aggressive compound that still gets the job done. If anyone on here has better recommendations, let me know.

I think we are all in search of that perfect pad: low/no noise, no glazing, good modulation, safe for street.

Blues: 0-550C MX72-Plus: 50-750C ME20: 150-800C You’ll notice as you go more aggressive the cold temps fall out of operating range, hence the inconsistent cold bite feel.

What about N39S?
Friction: 0,42-0,52μ Heat levels: 0-850°C They work from cold and have agressive initial bite with very strong overall braking power; however they are slightly harder to modulate. I tried them on Giulia QV (similar type of vehicle as M3 - weight, power, rwd saloon). Or perhaps endurance compounds (haven't tried those yet); like MA46B; they have lower braking power, can take a lot of heat, and should last 2-3x longer than sprint/track day pads like ME20, N39S,... But cost twice as much and won't really work well from cold. Last edited by lizardx; 04-14-2024 at 07:24 PM.. |

I think RS29s are it.

Are there any PFC or Ferrodo offerings yet? I cannot seem to find any. I think Ferrodo DS3.12 would be perfect for this platform. Pagid RSL29’s can work if there is no other option I will run them on my G87 and see, but the 3.12’s the best track pads I’ve ever used.

I just Finished Barber Motorsport 2 day event and the Blue stuff is great, but like yourselves trying to find streetable track options. Changing out pads after every event is no fun, even if you have the time.
It will be interesting if going to VS-5RS wheels will help with heat dissipation some. But having gone to supercar3 from PS4S and PZero will work them harder. VIR has some speed to get rid of for sure, but Barber never gives the brakes much time off. |

DS3.12’s have really nice bite when cold as well, although I wouldn’t daily drive on them. I have always used Girodisc rotors and they hold up no problem. In my experience there isn’t really one pad that can do it all. You can go something like a DS2500 but it’s really sub optimal on track and will get worn down very quickly if you put too much heat in it. I have never used RSL 29’s but looking at their graph they look more similar to a DS1.11 or a PFC 11 which are both good pads but less aggressive than a 3.12.

RSL29 Update
While doing track inspection, I took a couple of picture of the front pads. The following are after a single event at Summit Point, which I would consider moderate to highly tough on brakes. The wear is about 1 mm at this time, the RSL29s are holding up very well at this time.

2023 M4XC, I've ran Carbotech pad a few times on the track, which perform vary similar to Pagid RSL29. I've also run them on the car around town before switching back to the OEM pads, with no issues.

Folks, I run a fast F80 on Brembo brakes, peeking into the G8x world as a potential switch.
For 200TW tires, I would unquestionably try the PFC 08/11 combo, if they produce that (part numbers exist so that is promising). The PFC has been the Goldilocks pad for intermediate drivers on BMW for a very long time. I’ve run them on my E46, on the E90, on two iterations of F80. Put them on and leave them on for the season. I have a quick question for the collective - do you change the rear pads by yourself? Meaning, is it a DYI job?
