I was able to install them on OEM hats so I will be using them, yes. Not sure about the ZL1 though since rotor size is different.

So you just decided to ditch the oem rings or are you keeping them around? I am really curious how these will do at the track. I realize that these are a few pounds lighter and thus the unsprung weight benefit is four fold vs sprung weight; but with the loss of mass that would also decrease thermal capacity. I know the brake cooling on these cars is excellent, so I'm curious how the loss of thermal capacity will impact braking across a session. Will you be running this setup with the same pad at the same track to do some direct comparison between these and oem rotors. Also curious what the thermal paint on the rotors will tell you. Really looking forward to your results.

very good points. I also thought about that too but noticed that the OEM pin points were a bit different and thicker than the DBA rotors so part of that 1.3 lbs weight difference might be coming from there. In addition to that, material and cooling differences between the rotors may also be a factor. I heard nothing but good things about the DBAs but until comparing the two at the track it will be hard to say anything just yet. I will be using the same exact pads (I always use ST43s) and do my tests at the same tracks.

I still have the OEMs and am planning to use the DBAs once the fronts need to be changed since I don't want to change them back and forth. I never used thermal paint before but it may be a good idea.

From what I saw on the website those rotors should come with thermal paint on them from DBA, which should be a nice indicator for everything.

hmm good to know, thanks

How the OEM rotors look after three events (or maybe I should say two since the first two was not full event with many hiccups):

Plenty of life on ST43s as expected

[TrackClub]

Not too many heat check cracks eh?
Hard to tell from the pix exactly but are those GROVES on the rotors?

[glamcem]

Nothing besides some hair cracks
I couldn't feel anything on the surface I believe it's just the coloring

[TrackClub]

Awesome Really impressed this car can be beat up on at a track with everything "stock". Impressive!

[glamcem]

exactly, it's bone stock except the Motul RBF600 and ST43s and a bit more aggressive track alignment.

This is 3 full days with the Power Stop pads. Mine looked similar to Glamcem's after the 2nd full track day.

The Power Stop Track Day pads? If so, how did you like them? I bought a set and have them in my garage ready to go in.

They're good, I recommend them, and for the price they're a steal. Roughly equivalent mu to a Carbotech XP12, though it feels like their peak decel is in the middle of the heat range. Once I get them cooking the mu drops off a bit. Given the IR gun temps I saw in the paddock last weekend, the car needs better brake ducting regardless of what pad you run.

What temps where you seeing?
