Thank you for all the good info. Tell me is there really any advantage to cross drilled rotors? It seems that maybe they could cool down faster. Does it affect the wear rate or feel when braking?

I have driven my Boxster on solid, cross drilled, and slotted rotors. On the street, I don't notice any difference in braking performance or feel in regards to rotor type. They all work fine, cool fine, and have pretty much the same feel to me.

On the track, drilled rotors cool better and therefore have better feel when really hot, but they also crack and need replacement earlier than solid or slotted. Solid and slotted felt the same to me on the track.

The pad will make much more difference than the rotor because each pad will have somewhat different characteristics of initial bite, stopping power, and heat resiliency.

I always replaced pads without even resurface the rotors. And usually it was ok. Each rotor took like 3 to 4 pads before wearing out of factory spec (on the Alfa Romeo that I had). I never used race performance pads (unless on motorbikes), just regular road use Ferodo or Brembo ones. The Brembos usually were better, but they ran out sooner too. On my motorcycle, I had a problem with the 2nd pair of pads, they started to vibrate a bit under slow breaking.
