Anyone using these? Are they a good replacement from Oem? I track the z and the rotors are cracking bad.

Which DBA T3 variety are you talking about, the T3 4000 series single piece slotted or the T3 5000 series 2 piece ?? I have used both on my Z06. The 4000 series has much better metalurgy (sp) than the cheap Chinese crap rotors available from the parts stores. I got maybe another 30% life out of them before they cracked. Last year I switched to the DBA 5000 series 2 piece units. These are pricy, but last MUCH longer ! I have 8 weekends (50 sessions) so far on this set of rings, they show a lot of surface checking but are still going strong. What it really amounts to is how bad do you hate changing rotors ? 4000 series you are going to change out more frequently but cost less. 5000 series last a lot longer but are pricy ---
Brake cooling is VERY important to rotor life - if you don't have it add now ! There are several vendors that sell the 5000 series at a good discount off list - KNS brakes in NC has the best prices I have found.

I was looking at The 4000 series.

For near the same price you may want to check these out. http://shop.performanceafx.com/C6-Z06_c14.htm

+1 for brake cooling.

The 5000 are .100" thicker on the rotor walls (smaller air gap) than any of the other rotors (AP T1, Wilwood Spec37, Coleman, etc). All of them are around .300-.320 and the DBA are .410".

is that good or bad?

Mike.D

There's 10 rotors there, which are you recommending? I have cooling ducts if that's what you're referring too.

I agree

I like the flat face "non drilled or slotted". http://shop.performanceafx.com/C6-Fr...100166-167.htm You can give them a call and they can give you more detail on them, such as the rear rotors with or with out the parking brake, Performance AFX has great customer service as well.

I already have 2 sets of the DBA 5000 hats. Do the DBA hats work with any other brands rings?

CHJ In Virginia

The number, size of bolt and radial spacing are unique to the DBA rotors. Don't think that any other company's rings will fit their hats.
Let me know if you want to get rid of one set of hats, I would be interested.

Mike.D

Flat face? That goes against everything that I've been told and read about racing rotors.. Why?

Sir,

Here are some threads that may answer your question.

Thanks for the info, i just ordered a set of 5000s for the front and 4000s for the rear. W/HP Plus and str600 fluid. And stainless lines. Well see how much difference it makes.

We found the DBA rotors to be more durable and more consistent than typical replacement rotors.

So much so we had DBA make us blanks.

Corvette ones are next.

When will they be ready?

What is your opinion on pad wear of drilled vs slotted vs blank ??

And thanks again for sponsoring the Corvette Challenge

I am waiting for a quote w/ timing but at least 3-4 months from order.

I need to sell some of what I have first.

I would assume pad wear increases but given it's still used in high level racing I would assume the benefits are worth it.

I would not expect too much difference in various types of machined rotors unless the machining was poor.
