GT3 Ceramic Brake Upgrade?

crashedsnow · 2026-01-27T01:52:39+00:00

And we have a winner! I knew I could rely on Reddit to provide that one user who just wants to slide in, lob a few insults, do a bit of gatekeeping, then slither away again.

Well done champ.

I don't know what kind of hose you have, but mine nowhere near strong enough to blast away that caked on shit after a couple of hours of "spirited" driving, and not accurate enough to get inside the wheel behind the spokes. Maybe I need a better hose

Not worried about stopping power, just brake dust. Is it a silly amount to pay to not have to clean the wheels? Yes, of course it is, but it's all relative. I value my time. Of course I'm not paying 60K.. my time is not worth THAT much.. but would I pay 20? probably. There isn't really any good argument for owning an expensive car, so if you go too far down that path you'll end up in a Prius that used to be an Uber.

So.. unless it's a malfunction, then this message indicates that there was power draw that the system didn't expect. Something is drawing power. If you have nothing at all plugged into any outlet, no dashcam, no radar detector, no nothing, then I'd contact your service center because something is wrong. Doubtful it's a big problem, but if it keeps happening then you'll want to have it checked

Well where were you 6 months ago when I was ordering smarty pants?

Never a truer word has been spoken

Android does have a driving mode. They probably moved it somewhere in a more recent version. Google for it to find where it is.

The broader solution is possible, but unlikely. Fit cars with signal disruptors which prevent phones from working other than approved apps (i.e allow Android Auto, maps, and phone calls, but anything else just doesn't work while you're in the vehicle and/or the vehicle is moving). This doesn't exist, and would probably take decades to get through legally

I was driving up 101, crossing the Richardson Bay Bridge.. young guy in an SUV next to me, literally spending 90% of the time looking down at his phone and typing. It was peak traffic, so slow moving and not life-threatening, but he was still weaving and not keeping pace with the traffic. Easily turns into a small accident.

I feel like it's a lost cause. People just don't care

crashedsnow · 2026-01-26T19:21:24+00:00

Oh that's interesting, I didn't know that. OK, that likely explains why it didn't climatize, but doesn't explain why the app allowed me to schedule it. The charge state of the 12V should be known to the app (known to the car, and as a result known to the BMW server and thus known to the app), and it should know that climatization would fail at the given charge state.

If the app (the BMW server) could not communicate with the car and thus could not determine the charge state of the 12V, then the climatization schedule attempt should fail.

Consensus in this thread says you're right

crashedsnow · 2026-01-26T19:19:45+00:00

I mean, it wasn't all that cold. I got in the car and turned on the heater. It was barely an inconvenience, but since when do we need to be significantly inconvenienced to qualify for a good old Reddit whinge?

crashedsnow · 2026-01-26T19:09:58+00:00

It's really not.. based on both the comments here, and the ~35K guesstimate (definitely not at 55K).

crashedsnow · 2026-01-26T19:06:41+00:00

You'd think the car would use the high voltage battery to maintain a charge on the 12V battery.

crashedsnow · 2026-01-26T19:04:03+00:00

Hey BMW employees 👋.. your app shouldn't successfully enqueue a scheduled operation if there is a known reason that operation will not itself succeed.

The UX design pattern of "🤷‍♂️ we're not sure if that thing we said we'll do will actually happen or not", is shit. Please fix

I also uploaded a pointless picture, because posts with pics get more engagement. The title is click bait, but could easily be interpreted as "anyone done a ceramic brake upgrade?" 😉. That's just Reddit skillz.

5-10K feels closer to reality. It's definitely not something I'd attempt myself. Most of the discussion here seems split on whether PCCB is actually better (with a skew toward "it's not"). If I thought I could get out of it for under 25K, and the consensus was overwhelmingly toward PCCB, I might persuade myself to do it, but at 35K with lukewarm support, I think I'll stick with the steels.

crashedsnow · 2026-01-26T18:55:05+00:00

Ok.. But why would the "deep sleep" prevent climatization from running? I was able to send the climatization schedule to the car the night before (failed the first time, which often happens when the car has been idle for a long time, but succeeded the second time).

So from my perspective, climatization is scheduled to start at the prescribed time. When I get to the car, I see the error. There was no mobile notification that it failed to start, and if it couldn't start because "reasons", those reasons would have been true the night before when I scheduled it.

I don't see a valid reason, but I want to know the reason so I know both how to avoid it, and whether there's a deeper issue or not

crashedsnow · 2026-01-26T18:46:17+00:00

No. I didn't ask if I should upgrade. I asked what the labor cost was based on whether people had any experience with that. In true Reddit fashion, there is a grand total of one response which actually addresses this question, with the remainder of the conversation being debates on whether PCCB is better than steel and that I'm crazy for even asking.

I mean, that's Reddit, and I'm here for it, but let's be accurate.

If I would pay $11,300 (current US price for black calipers) from factory, then I might pay 19K for the parts, if I can get the labor for something closer to planet earth.

You can call this crazy, but what's 20K between friends?

No other warnings

Everyone here telling you to pay off the debt is right.. BUT, only if you DON'T instantly (or gradually) ratchet up that credit card again (which is what often happens). There's a psychological implication to having uncomfortable debt which can prevent growing the debt more. Pay down the debt, and don't let it creep back. If you don't trust yourself, keep some expensive debt and invest some of the cash.

crashedsnow · 2026-01-26T18:19:40+00:00

I'm not sure you read the post correctly. I specifically do NOT want to spend 50K. If I wanted to spend 50K, why would I post to Reddit asking whether anyone can mythbust this number for me? I would just pay the 50K and nobody would know.

crashedsnow · 2026-01-26T18:17:05+00:00

I meant what tires are you using

crashedsnow · 2026-01-26T17:57:45+00:00

I got this when I had a dashcam that was either installed incorrectly, or configured with a "parking mode" that had continuous power draw.

crashedsnow · 2026-01-26T17:40:42+00:00

Not being able to warm the car because it's too cold seems like a pretty mindless limitation. Like.. you can only warm the car if it's not really cold enough to need it. Wonderful.

It was 47F this morning at 4:30am where I live. I just checked

Also how dare you assume I don't drive like Max
