Anyone have experience with both on the track? I upgraded the brakes on my C5 to C6Z calipers and DBA 4000 slotted rotors last year. That combination along with spindle cooling ducts got me through 6-8 HPDE and AX events last year before the fronts cracked.
I'm considering the OEM C6Z rotors due to cost. Will they hold up as well as the DBA's?

Nope. Initially I used 6Z stock - went thru them a lot faster than the DBA's. Stock cracked up more easily with all of the little holes - liked the DBA's much better - felt I got better braking from them.

Are those two day or one day HPDEs. I would get around 5 track days on a set of OEM Z06 rotors before they cracked. That was using Cobalt CSR and Hawk HP Plus pads. A more race oriented pad may reduce the rotor life span some. AX doesn't really affect the rotors that much since you don't get them very hot.

Why do you say that? I have seen fastrash on track and he definitely uses the bakes to their potential. If he gets more life out of the DBAs then I would say they are better.

I've been using the stock C6Z rotors on my car for the last 3 HPDEs (2 day events). No issues at all, minor SURFACE cracking (not the deeper cracks requiring replacement). DBAs run what, about $380 a pair? My last set of OEMs I got from Gene Culley for half that. If you're getting 6 track days out of those, you'd need to get 12 out of the DBAs for it to be a wash.

Thanks for the input. I think I'll stick with the DBAs.

Are you using 13" rotors?

I've used both on my C6Z06. I just went back to the OEM rotors. Perhaps the DBA4000 would last a bit longer but not much at all. As far as performance, they were very equal the best I could tell. So for me it just came down to cost. My car is stock except for brake pads (Carbotech XP10) and tires Hoosier (R6's). Side Note: I think the OEM look better too! but that's a subjective thing that people will differ on. Heck, it's all subjective when you get down to it. I'm one that has to try different things for myself. You really don't know until you try it for yourself. Just, do and use what works for you, we all are different and what works for me might not work for you and vise versa.

$266/pr - knsbrakes.com (forum vendor) good deals on pads too or Ken over there given me some nice bundle prices too! Plus you can get plain or just slotted rotors which will last better than drilled and the vanes are going the correct direction unlike the stock ones.

I don't see the vanes as an issue on the OEM rotors. If they were an issue wouldn't the right side wear pads out sooner, wear out the rotor sooner or crack the rotor sooner. They seem to last the same on left and right side in my case. What has been your problem caused by the vanes? I understand the theory of how the vanes are suppose to work but in my real world, I don't see any difference.

I track every track mile on my consumables. Running Hallett which is very hard on brakes and Raybestos ST-47 or Wilwood H (same pad material) I get more track miles out of the OEM rotors. This is not a subjective comment.

I originally ran multiple sets of the OEM rotors and then ran 3 sets of the DBA's back-to-back. Switched back to OEM and every set of OEM's lasted longer than any of the DBA's.

Also, every one of the DBA rotors grooved like an LP record (i.e., album).

For me the DBA rotors were a waste of money. A number of other C6Z guys on here experienced the same results.

What do you guys think about these? http://shop.performanceafx.com/C6-Corvette_c11.htm
I have them on my 07 C6, they are lite and last a long time, at least for street use. I have not done any track time with them.

I've had good luck with them, I run the AFX 2pc on the front and the DBA4000 on the rear for my track rotors on both the z06 and the 68 camaro which has the same brakes. I would have done 2pc rear but there isn't much weight to be saved out back.

I'm surprised so many have good luck with the OE drilled, I never tried them on the c6z after cracking drilled rotors on the c5 when I first got into HPDE's, I never went back to drilled rotors. But if it's cheap and it works, good for you!
