Default Ceramic brakes and track days?

For those of you who have taken your M3 with ceramic brakes to a track day, I am wondering how it performed and how the ceramics compared to steel brakes. Did you need to upgrade pads and if so which ones are safe to use with ceramics? Is the ceramic brake upgrade worth the expense? How do the rotors hold up to the abuse? I cannot imagine those are cheap to replace.

I have done many track days in other cars with steel brakes and I think the car would be fine with steel brakes, but I am trying to justify the expense aside from the lightweight and "cool new tech" factor.

Thanks!

Steel brakes are fine. No need for ceramics.
You see GT3 and Ferraris guys replacing ceramics for steel when they track their cars, because ceramics are way too expensive to replace when they are worn.

That's interesting. I had wondered about that since I usually do not see anyone running ceramics at track days. Good news too as that will definitely save some $$$$.

So what is the point of having ceramic brakes if most people do not even use them on the track? Is it just to be able to brag about having them? Haha!

Anyone running ceramics on the track that can comment?

Thanks!

Just bragging, that is all.
For the casual track day, and street driving, steel brakes are more than enough.

Ceramic brakes break easily (chipping), are very sensitive to oil (if you drop oil on it, you can replace them), and cost way too much.

They certainly are a thing of beauty and are very fade resistant, but the downsides are just deal breakers imo.

I agree with you Flow. That is good to hear about steel brakes as that will save me lots of money down the road.

So what happens to carbon ceramics if you get oil on them?

ceramics are great because they have almost no dust, higher heat capacity, and are lighter than equivalent cast iron brakes. Street life is also about 2-3x the cast iron rotors.

For the M3 the ceramics are also a larger rotor than the standard brakes.

If you're just doing a few track days a year the ceramics make sense. If you're doing 15+ get a real BBK. If you're just doing street driving I would probably stick with standard... cost after $150k miles might be a wash but its not likely anyone will keep the car that long.

Stock rotors and PF pads work just fine.

I agree with you guys about being fine with the steel brakes and maybe even adding some brake ducting.

Is anyone here actually tracking the car with carbon ceramics? I am curios to hear your experiences and comparison on track with the steel brakes. Also what pads are you running on the track with ceramics? I usually use Hawk DTC-60's on track, but I would imagine those would tear carbon ceramics to bits.

Flow- what happens if you get oil on carbon ceramics?

I saw that in a Road&Track video about the cost of owning a supercar. They said you need to be careful not to get oil on them or otherwise you need to change them.
They are protected during service to avoid any chance of getting oil on them.



But I can't find anything to back it up online, so it might have been wrong.
