His mods are simple and reversable. The HAS kit it the biggest PIA to reverse but you can still revert it back to factory if you want.
I would hardly call a stud conversion kit, spacers, CF strut tower brace or a HAS kit warranty voiding things to do to a car. Even the tech didn't go that far. They just asked he put it back to stock so they can diagnose it. The OP said he was having this issue before modding anything. I would say if that's the case he should have had it addressed before doing anything to the car to avoid the hassle. That said, it really matters who you are dealing with when taking it in for service. If you get someone that's not willing to help you take it somewhere else. |

So as im going through the run in process, I decided to test this Apex theory of brakes squeeling with forged wheels. Plopped on my Apex forged wheels, sure as shit, brake squeel. Took them off, brakes are silent. Never would have guessed that.

Speaking of which, can people who have tried low dust pads chime in with which ones they’ve switched to and how it compares to stock and if they recommend it?

Simple logic eludes him it appears. There are simple things to try and assess before engaging the dealer.

I can't find the post, but I remember APEX or a BMW SB mentioning/recommending some sort of disk insert to place between the brake hat and hub. (sorry, can't remember more details) Maybe you can look into it as a way to quiet everything down. EDIT: I think the part number below is the friction ring to use (from BMW SB) Part # 34 10 6 884 839 Friction Ring wheel bolt pattern 5x112 2

It is still interesting to see if folks having more braking noise than others have spacers and/or aftermarket forged wheels.

The brake squeal on my M2 is unbearable if the windows are opened. I can barely stand it with the windows closed. The brake dust is as bad as any car I have ever owned--in fact, it's probably worse. No mods on the car at 1k miles, though I did hardwire my V1 to the overhead console. I didn't use a zip tie so it is quite reversible. I don't like driving the car around town because it is a head turner--people don't turn to look at the car, they turn to find the source of the painful squeal!
My 992 C4S brakes have been silent since day 1 and the steel brakes incredible. I don't understand how anyone here can say there is a give and take between performance stopping, noise and brake dust. Porsche has it figured out. Why can't BMW do the same?

Do you have any spacers or aftermarket wheels, just out of curiosity?
Try the bedding procedure....or.... If you don't plan on tracking the car, switching to a more street focused pad may be indicated.

Yeah I don’t understand why he didn’t get it taken care of before adding any aftermarket things. If I had that issue, I’d drive my ass up to the dealer. I guess it’s decent YouTube content. I am subbed to him but when he said that it’s been going on I literally WTF’ed out loud 😂

Finally got around to swapping the pads. Odd observation. Front rotors are wavy to the touch which I think caused to the pads to go bad since it's an uneven wear. I know someone mentioned these M2's sitting at the port for a long time before getting transported to dealers which caused the rotors to endure a large amount of rust which lead to them being compromised.
Anyways swapped out some used pads from a G80 M3 with 1000 miles. No more vibration but my guess is the wavy rotors will ruin those too with time. I reached out to the foreman at my local dealer to report this and will be jumping on a call with him hopefully tomorrow. Mods or not, 15 hours at the dealership and they didn't inspect something that was so obvious...because of my mods. Anyways will update you guys soon hopefully and will be filming a follow up video. |

If front rotors are wavy to the touch then there is no way new pads are the solution. Warped rotors where the amount of warpage cannot be detected by hand will cause significant vibration. Not sure what you have going on.
So, going in a different direction, these are two piece rotors right, I mean they have to be with monoblock multi-piston calipers. What are the thoughts that the bobbins are "sticky" Common problem on motorcycles.

Wheels and Brake Rattling When Coming to Stop
Here's video of the rattling. He's got spacers and lowered. Oh, and CF struts swapped out the steel ties OEM. Long story short, the dealership would not touch it until he put EVERYTING back to stock including the engine bay struts. Seems like dealers are being really assanining.
Didn't post a follow up. I spoke to a CA and he said that cars sitting at port are rusting up and you need to do a few hard stocks to get rid of the buildup. Not sure how you do that in break in when you're supposed to go easy. That's last I heard, curious if anyone has experienced and how often it has happening with new deliveries and how it was resolved.
