slotted and cross driller rotors do NOTHING for removing heat.

when pads heat to the upper limits of the temp range for the pad they start to "gas" or break down and release a vapor/gas that can get caught between the pads and rotors. this basicly kills and sort of brakes you had and often feels like brake fade. slotting and cross-drilling gives that gas a place to go.
there is no other reason for doing either to brake rotors.

and like you said, the only way to gain the benifits from drilling or slotting is at the track.

on a basicly stock or mildly modded focus or even a Focus pushing upwards of 170-200fwhp all you need is a pair of Brembo blank rotors, Hawk HPS or HP+ pads, a set of stainless brake lines and some quality brake fluid. this is MORE than enough to handle anything you can throw at your car on the street and AutoX.
for extended track use real big brakes(like a TCE kit) are a must.
for light lapping days i would suggest the above basic setup as bare minimum and something like a SVT front brake kit, or Bat kit as "suggested" with a real big brake kits as "ideal".

EBC pads are nothing special. the green stuff are designed to dust less and offer marginally better bite than OEM. redstuff is a much btter performance pad from EBC.

Hawk pads are what we suggest as they are a killer pad at a very nice price.
