These are stock E46 M3 brakes. I was quite impressed.
Lap after lap with these disks lighting up the track.
I want to see it on an NSX too. Anyone?
Does anyone have NSX pics like this? (Image)

my guess would be stock due to the size of the callipar, it looks rather large.

The rotors don't seem that large. If I had to guess, I'd say there were stock brakes. 
I'd also like to see NSX brakes glow! That would make a great pic!

They are stock.
I talked to the owner.
Not an NSX but glowing
Dude that's bad ass!!! I've never seen any pics like that before. Yeah, let's definetly get some NSX pics posted!
More ALMS Pics, no nsx
Here are some of the pics I took at the 12 Hours of Sebring this year.

I've seen it in hi-speed chases before, but thats usually after they've gone through the tire and rim!
Racing Brakes...
are made to handle this kind of heat without warping. Floating Rotors help because less heat is transferred to the hub/wheel. The materials used in race brake rotors is pretty much the same thing you get when you buy any aftermarket AP Racing/Brembo or TarOx brakes. I wouldn't try running a 12 hour race on stock rotors and pads. That M3 picture probably does have stock rotors, but most likely he's running something like Pagid race pads. I had them on my Z3 and I'll tell you they were incredible.

Any body ever seen the NASCAR or CART "in the wheel" shots where flames come shooting off the pads in hard braking. That makes the red hot rotors look tame!
After coming off the track once, I looked down and my brake pads were smoking! (and that was after the cool down lap and everything) He he.. that was cool.. wouldn't be surpised if the rotor was glowing, but no one took any photos...
Not an NSX, but still a cool night pic.
Is it me or
does it look like the Ferraris in those pictures brake proportions are slightly off. Everyone else is glowing front and rear. They are not. There is a small hint on one, the other looks cool as ice.

My friends Talon used to glow and throw flames going into 5 @ Road America. Stock rotors, with Porterfields. Smoking pads is nothing. I once switched pad compounds mid day in my Integra, little did I know that they wore 2X as fast as the others that I was used to........I put 2 Wilwood pistons THROUGH the metal backing plate and was running piston on rotor!!!!! I still have the backing plate hanging on the wall in the garage with 2 perfect circles missing!!! I also used to crack 13" rotors from brand new to toast in a weekend. I switched from drilled to slotted and got 2 weekends out of them!
Its pictures like above that tells you why you should NOT hold the brake after sessions!!!

Re: Is it me or
The other cars you see are LeMans Prototypes running carbon rotors, and the brakes on those cars are working much harder as the prototypes are running at speeds nearing 220mph! If you watch an ALMS race, you'll see the the Porsche brakes don't ever start to glow. The front brakes always take more of a beating, so it's not likely you'll see glowing rears on cars running metal rotors in GT or GTS.

Fun Post Guys!!!
Cheers to you guys that replied w/ pics of the R 8's and Bentley prototypes. Those Pictures are Bad to the Bone!! reminds me of those old days At Del Mar G.P. and 24 hours Daytona.
These prototypes ar where the NSX technology came from w/ Parker in the early days @ Comptech.

The Bias appearance that you notice in AMLS prototypes and GT classes are differnt for several reasons... Yep their is a differnce in the compounds of the pads obviously, and the rotors on prototypes are Carbon/Carbon (not carbon fibre as most people assume). Carbon is grown, simply stated, similar to growing rock candy. Once grown it is then modified in many ways including Mill work to the form of rotors, which don't wear much, and sustain huge temps, but are useless in low temp applications such as oval tracks, where the teams use "Iron" or steel as others state.
Depending on the brake "package" the temps will vary. usually teams will try to duplicate the temps front and rear so the pad and tyre compounds can be the same f/r. Often there is no choice in compounds f/r depending on rules and $$.
Possibly these Porsches and Ferrari's have no "glow" on the rears rotors,,, It isn't that they are not getting enough rear brake, or the bias is wrong, but possibly the rear rotors and or calipers are larger than the need, and thus run cooler. ( I thinks the R8's use a 15" front rotor and a 13" rear. Again Ideally most teams opt to get f/r close in temps to each other. Also as stated in above post, "floating" rotors tend to have cooler temps for several reasons. One of them is that the hardware for the rotors ("bobbins"), which is the hardware that holds the rotors to the "hats" is made out of Titanium which conducts heat Much, much less. Racing brakes also use Ti "pucks" which do the same w/ temps from pads to pistons.
Oh also, these cars see sugnif higher speeds than 220 also...Especially at Le Mans.
Thanks for the cool post guys. Best one I've seen in ages!!

Agreed, this is a great thread. And great replies especially from the last couple posters.
I've had my front rotors glowing just once (from what I was told) - straight from a hot lap into the hot pit to determine tire temps. This was with the stock sized rotors, Carbotech Panther + pads, and R compounds. Sadly, no pics. I can't believe no one has got any pics of an NSX with glowing rotors though.
The best opportunity would be an evening shot of the DAL Motorsports NSX. Stock sized rotors and a fairly long race.

not to mention that most of those pictures are from the 24 hrs race, they don't run the car in 10/10 all the time, come to think of it, since the open cars are faster and much more stable (thanks to the tremendous down force..) at the end of the straght, they would brake much harder than the Ferraris/Porsche... so you will see them had all 4 rotors glowing...
I remember when even the "sprint" raced touring cars does have glowing brakes too... and I also suspect all the pictures above were taken at the corner exit, I'm pretty sure those rotors will cool off (not glowing anymore) just couple hunderd yards as soon as the speed picking up and air rush in.
Speaking of the flame/ sparks, it could very well be the by products of slotted rotors and hard compound metallic pads... I believed the nsx shot out on mountain roads in one of the Best Motoring episode, the NA1 type R is doing the same thing too, very cool to watch... I would say when the rotor is glowing red, it's running the brake's full potential, anything beyond that would be brake system failure...
