Raybestos rotors. No longer having Drilled holes?

Haha, no problem. I always like to chime in on brake or suspension posts. BTW , do you know of any track/race pads that still de-gas? I swear most of them don't do that anymore.

Mike I agree, ANY type of hard track use (with the exception of drag strip use), and the repeated heat cycles will certainly push the limits of the OEM rotors. That being said, I think you did good with 44k on them, I don't think I have ever had 44K on any of my OEM rotors on any of my vehicles, ever.

My front rotors didn't last that long running at CMP. I had cracking after the first day, and by the third weekend, the cracks had grown beyond Lexus published limits.
If anyone has solid rotors and does not want them, I'll be happy to take them off your hands.

Still want to know if there is a reliable source for slotted/dimpled rotors. If not I will just go back with stock Brembo rotors, for the daily driving of 50k+ miles they have held up just fine.

I had the same issue with the Raybestos rotors. Ordered a full set from one company. The rears were correct and drilled, the fronts were not drilled. I sent them back and went and ordered a front set from rock auto. They were also incorrect and not drilled. I think Raybestos has mis-labeled a production run of their rotors it seems like.

Cryo rotors are snake oil, IMO. It's possible they might last a bit longer purely for street use but they have repeatedly shown no benefit in terms of added life for track use. Either way cryogenic treatment adds 50%+ to the cost of the rotor in most cases and they'll never last 50%+ longer than the same rotor thats not treated.

Cross drilled rotors are thing of the past sre no longer necessary. Reiterated earlier statements one of the primary purposes of crossdrilled rotor were for the out gassing of the brake pads but with the Advent of new materials this is no longer an issue with modern brake pads. Cracks form on the Cross drilled sections, and will actually reduce your pad life as well. Just to give you an example F1, NASCAR ,Autocross, Drag racing and other primarily use either solid rotors or slotted rotors now. Here are a few pictures of examples
Various types of racing these are primary NASCAR rotors
