With the amount of rust, corrosion on the rotor and hardware looks like these have been around for a while? I've never kept rotors on a track car long enough for them to rust. I've run DBAs for years on my other track car (C5Z) and they are a huge improvement over stock. Used to get close to a full 10 event season on them with DTC70 pads, before they cracked. Never saw tiny cracks like those. Not saying Giro might not be better, but DBA is far from junk. I'm on my 4th event and 2nd set of pads with them on the 1LE with nothing more than minor heat checking. First event was WGI with both my wife and I driving the car with DTC70 pads which are notorious for being tough on rotors. She's a novice and probably a little harder on the brakes. (and if I want her to know I said that I'll tell her......)

I used to run DBAs on my C5Z as well. However, after they outsourced their manufacturing to China, I stopped purchasing them, as they didnt last long at all.
OEM Brembos are made in USA. They hold up extremely well imo. I personally dont see a reason to pay the same price for aftermarket rings only vs a whole oem assy.
But that's me. Cheers! PS A novice being possibly harder on the brakes is a myth. Unless they stop the car before each corner entry

Everyone has their own experiences and biases. My experience with DBA has been very positive. I never experienced a change in longevity with their C5 rotors between 2009 and 2018. The quality of their replacement rings for this car remains to be seen, but so far they are holding up better than the stock rings.

As far as "myth" is concerned, my experience and observations with over 12 years in the right seat coaching novice students on appropriate braking points, intensity and duration, as well as years conducting tech inspections and having to tell novices they won't be able to drive today unless they brought new pads, would also seem to differ from your experience.

Cheers!

I certainly respect your opinion. I had started tracking my C5Z a few years before you did yours and by all means I have noticed a difference is ring longevity when they offshored production. Having said that, i haven't used DBAs for a long time now as i had switched my Vette to AP. So i dont have any recent data to be fair.
As far as the myth goes, i know of no reputable club like PCA or BMW that requires novices to switch to DOT4 fluid as a pre-req. Other than bring a car with 50+ % of pad wear.
Meaning a vast majority of novices run on oem fluids.
If they used the brakes so hard as to be * harder * on rotors vs fast experienced guys, all of them would be boiling the fluid and crashing all over the place as a common sight at majority of HPDEs. Thankfully it is not the case and there is a reason for it. Just saying

Peace

Agreed, Novices will be going much slower than the advanced guys. While they may be on the brakes sooner and longer, the brakes are performing less work because the slower speeds are less kinetic energy. (see also: less heat, less wear)

An intermediate guy who is starting to get some good straight away speed but still over braking probably fits the scenario better than a novice.

Pads used OEM and DCT 70.

Will be ordering Girodisc now and hope they fare better.

How many track days on those rotors?

[carguy55]

Got my DBAs. Will be interesting to see how long they last with the DTC70, Ti shims and SS track duct kit

DBA vs Giro video

They both have pros and cons.

Can you elaborate? Curious to know.

[Vtor_ZL1]

Is one or both lighter than stock ?



Camaro ZLE 24.xx lbs
Z06 - 19-20 lbs range
DBA
Gerodisc ?

[carguy55]

1 con, slots eat your pads quicker

[Dave-ROR]

IMO just run the stock ones. I got plenty of life out of mine and I'm not exactly slow.
