Cryo / Slotted Rotors
I'v done some checking and it's a bit pricey for the Cryo Slotted Rotors and the Hawk pads. I'm definitely willing to spend the money if it's worth it. As you all know, the EX needs some more braking power. Any thoughts, complaints, etc...

i put them on last month and so far so good
a lot of people like the Brembo rotors too- thats probably what i'll do next since the powerslots cant be turned (i dont think so anyways)-hopefully after a lot more miles than the stock lasted

now i will preface this with - i do not know how the theory applies to the X,
but in car rotors and pads - the drilled and slotted rotors are useful for heat dissipation (sp) as the hotter the brakes get, the les stopping power they have. However, they do need a certain ammount of heat to be effective. In car applications, the tend to not work as well in cold and wet, because the slotts that would usuallt take away the heat, do their job and also give the water a place to go while reducing (ever so slightly i know) the braking surface. Ive found that those performance items were not as goon in the cold and wet / snow, which is half the year here in chicago.
Im definately willing to hear others feedback on what they have found, as i am thinking about a Brembo upgrade perhaps as well.

Even though this topic has been beat to death I want to interject something.
Getting water on rotors is a very hard thing to do at speed. Sure, if you're going through a deep puddle at crawl speed but centrifugal force and the entire design of the brake rotor prevent (for the most part) water ever getting on the rotor...again...at speed...where the braking performance matters.
Slotted rotors, while they do have a minimal reduced surface area, help expel the gases but more importantly (I think) with each pass of the slot over the pad it creates a new leading edge and helps improve braking feel.
There is nothing wrong with the Excursion's rotor or its design. The problem lies with the pad material. Change the pad, bed it in properly, use your brakes correctly and you'll not have any issues with braking performance, brake dust or supposed "warping".
FWIW, it is just the ceramic based pads which give very poor "cold" performance.

The one thing I did notice with the Hawk pads and Cryo rotors is it does take longer for the pads to properly bed as the directions tell you, so be patient.
OBTW - Hawk pads significantly reduce brake dust compared to the OEM Ford pads. I was so impressed with them, I put them all the way around on my ZO6 and what an inprovement.
