Nowadays you do not need crossed drilled rotors. Slotted rotors I still question.

Pads don't gas like they used to years ago. Yes some companies like Porsche still use them.

But the less brake rotor you have (due to cross drilling) the less surface (or cooling area) you have to keep your rotors cool. This contributes to less brake fad. Ask anyone on the Honda Challenge team what they use.

Remember brakes need surface area to stop better, which is why people upgrade to bigger brakes. More surface area equals more cooling area to keep the brakes cooler which equals more stopping power.

I used cross drilled rotors and AEM pads at VIR in February (50-60 degrees out) and I still faded my brakes on the first day. now granted I was using stock OEM honda brake fluid, which boiled too.
