My understanding of the purpose of either drilled or slotted rotors, is to allow the superheated gasses, which form between the pad and the rotor surface, to vent. It supposedly prevents the gasses from floating the pads. A dimple does not allow escape of the gasses.

I'd honestly stick with the stock brembo rotors. From friends that track their cars they tell me that as long as you have a decent vented rotor, you can use upgraded pads with a fluid change, season them and you're ready to tear up the track as far as stopping power goes. Here is a track prep guide that should translate over to a 5th gen if I'm not mistaken. https://my.chevrolet.com/content/dam...tion-guide.pdf

I realize its a different animal. But the grandsport corvette has drilled rotors from the factory. Atleast thats how my dads 2017 vette came. Wonder why they are so bad?

Each hole drilled in a brake rotor represents a location where the stresses from thermal expansion are intensified. This is mainly a fatigue situation where many low-stress cycles can be withstood but far fewer high-stress cycles. Each cycle is a "thermal transient event", and I used to do a little thermal transient analysis and quite a lot of fatigue evaluations back when I had a day job (not automotive-related, but the principles are the same). There was a time when venting pad off-gassing was the more critical need, when pad formulations weren't what they are now. I remember a couple of cars that only half a dozen snubs from about 70 down to 40 in quick succession was enough to fade the brakes into near-worthlessness. I don't think you can even find a new car that bad any more. Norm

Simply search for "cracked rotors". Now, many of what's pictured are blanks, but that's expected as only track-guys tend to crack rotors (outside of neglect, abuse, or accident) and track guys tend to use blanks.
But take note of where the cracks on drilled rotors start: https://www.google.com/search?q=roto...=lnms&tbm=isch

I have Stop-tech drilled & slotted rotors on my '14 LS , but I don't track or drag race with it, I have no issues with them . Only reason I got them was I liked the look of them.
