Actually it has a little label on it that came with it that said do not attach to glass. Unless it's a different than the one my friend has, but they look identical.

Concerning the brakes. The rotors are not the problem. It's the pads. Get better pads. I found a overall good pad for the street and occasional track use. Ferado DS2500s are great for this. After several track events (some in 100 degree temps), and autox, and hill country cruises the brakes are still going strong. I also have SS lines and Motul 600 fluid.

My brakes got so hot that my Brembos went from Gold to Brown for a while during that event then turned back to gold. The caliper themselves was 800 degree's when I tested it but the brakes were holding up! Still on stock rotors after 16k of miles.

The same thing happened to Chris with HP+ on his car...same symptoms same everything. I don't think its the pads. The pads aren't causing the rotor to score like it does. You really think DS2500's are good? Come on, they aren't even meant to be track pads, thats what the DS300s are for. The 2500's are high performance street pads.

If this

Is happening to two different people with two different pads, then I'd say we have a problem in our hands. Also if I remember right, it happened during one of those Car and Driver type reviews a while back.

Yeah, everyones brembos do that at trackdays. My STI ones did too...except not the whole caliper, just the lettering goes from red to black....and stayed black. It doesn't turn back once it does that.

I would think if it is two separate people with different pads then the rotors themselves may be to blame. Got an idea for you RCZ. I'll send you my non-sport brakes and you send me your's. That way you can compare. And since the sport brakes suck so bad you can keep mine. I'm just nice like that.

no

But I will give you guys some track videos. Be patient, they aren't done processing. When they do, they will work.

Here's an edmunds test with the same rotor problems. 2009 Nissan 370Z Touring: Track Tested! | Long-Term Road Tests Blog on Edmunds' Inside Line

How do you think aftermarket rotors would fix this problem?

they dissipate heat better and are made of much better materials specifically designed for higher temps.

Hmm, I was not aware of the material difference. For most instances, I was under the assumption that plain rotor blanks would be fine on the track.

yeah it should be fine for our application, but obviously its not from what we've seen so far. I am just going to get some slotted stoptechs or some DBA. PF makes some nice quality 2 piece ones.

I need some standard one piece rotors for competing in stock class at auto-x, but I'll be interested in some nice 2 piece rotors for the track.

I sent an inquiry to DBA USA.

Edit: I couldn't find any rotors from PF even for the 350Z so it doesn't seem likely they will make any for the 370Z.

Sorry for all the questions, but RCZ, why do you think you did not have any rotor issues during your other track events? And though scored, will the rotors lose any braking ability?

Also how do the stoptech aero-rotors compare to the PF and DBA rotors?

Last time I was on the track the car wasn't fully broken in so I wasn't pushing it anywhere as hard as I did yesterday. I was actually getting on them yesterday on a couple corners where I needed to and they did not hold up well.

Yes scored rotors will loose some braking performance. They do eventually get smoothed over again though. I have about 80% of my brakes back...they get a little better every time I drive the car, but I think they are doing getting better...

As far as the rotors go. I think the DBAs are the best. PF's and stoptechs are around the same. The Aero's look nice though! I will consider them!

Incorrect. The DS2500 are Street/Track pad. The DS3000s are Track only pads. Been discussed on the Z forums for a while.

I had HP+ on my G35 and they did that crap to my rotors when they faded. I will never use Hawk pads again because of that.

Either way it is starting to look like a soft rotor issue.

I have the USA rep for DBA checking with DBA in Australia on ETA.
