So there was a deal on them and thinking well as long as I get a decent season out of it or at least half a season it was worth 300 something for a pair.

So these rotors have 4 days at Summit Point and on the 4th day at VIR this happened.

They’re for street wannabes. Sorry it happened to you.

Yep. I knew they weren’t great. Just didn’t guess that bad. Lesson learned.

Looks like the standard brake system with one piece rotors. The failure is simply because they got too hot on the track. Likely would have been the same for OEM rotor of the same design. I would not blame this on PowerStop. You simply asked the system to perform beyond its limits.

Not sure what year your car is but you be need to upgrade the entire front system to the floating rotor design. That will mean different calipers. Floating rotors allow the braking surface to expand and contract separately from the rotor hub. The one piece rotor you have now cannot do that.

That's not strictly true, there are two piece rotors available in 325mm oem size. DBA and AP for example. However you will probably find C5 calipers just as inadequate. (the c6 ones are better) and if you have more power than stock you will want a bigger disc anyways. If you have a C6 you can get the j55 caliper brackets (which gives bigger diameter) and giro discs. Unfortunately, any two piece discs will cost a lot more than $300.

I still recommend the kns/dba cheap blank rotor. It look about the same as power stop and they also crack up eventually but at least they're a lot cheaper... https://knsbrakes.com/products/car/106212_2004+Chevrolet+Corvette+All+Model s/items/series/815

Mine is a 2020… I ended up getting a set of Girodisc 2 piece rotors for the front and the back. Hopefully that helps clear things up a bit. We shall see.
