And here's how the thermal paint on rotors look like:

according to this guide the rotors temp reached somewhere between the yellow and white colors which means at around 570-580 C degree (about 1050F). As I mentioned before, this track is very abusive on the brakes and I will find a way to feed some air into the knuckle/rotors area to keep the temps in check


I didn't notice any fade issues and ST47/ST45 combo seems to be working just fine. The initial bite and modulation a bit different than the ST43s though

Thanks for the info Gentlemen,

It would be nice to have the Ambient Temps and the Number of Prior Runs(to adjust for Heat Soak), when these Temps are taken.

You're welcome. In both days, temperatures were in low to mid 70s. At ORP, I used them for about 5 sessions and those are really long (at least 30 mins) sessions with open track format. And about 4-5 sessions at the second event (20 min sessions) . It looks like they hold up a bit better than the OEM rings but it's too early to tell. I hope that helps

glamcem: Thank you for the post. I'm going to try out DBA52770.1LS/RS. I used DBA 4000 series on my C6 and loved it.

One question: You said it is recommended to replace the bolts. Do you have the part number for those bolts? Did you actually replace them with new ones?

Thanks!

You're welcome. I didn't replace the caliper bolts personally but I used Nordlock washers and torqued them to 90 lb/ft . So far so good

Awesome!!! Thank you!!!

I just purchased these rotors from autoanything at great price, and thought I would share with everyone.
I paid $568.48 with free shipping for both Left and Right.

Weird thing is, you can't search it on auto anything's own website with part number, but if you just google the part number, auto anything link will be listed. Follow in the link, add one rotor, and open one more tab and do the same for the other part number. Then use promo code "406820" at check out for 20% off. You just saved $142.12 for the rotors!

Hope it helps.

That's cheap indeed. Thanks for the information

About 3.5 events on the rotors so I wanted to give some update
They look like they hold up better than the OEM rotors

[TrackClub]

That's a lot of heat checks after 3.5 days. NB My stockers lasted me 15 days (and 5 different tracks). Let's see what these look like on day 15 and then compare pix

Cem said 3.5 events, not days.

You're right but as far as I know Cem refers to days as "events" (based on his prior posts).

Gotcha. Here are mine after 11 days on track. I’m happy with the DBA’s, I’ll keep using them unless GM starts selling blank rotors only less the aluminum hats for cheap.

[TrackClub]

Hmm that's about the same as mine I guess. I was tre happy with 15 days from the stockers thats for sure. I hear ya re discs vs a whole assembly tho. If I didn't have to import them from S of the border I'd likely go this route too. But for me getting a whole brake system from GM (incl hats) is the same $ (about $700USD).

Has anyone measured temps with caliper strips and rotor temp on the OEM and DBA rotors (DBA rotors come with temp paint IIRC).
