Copied and pasted from Wilwoods site:
"Q: Why are some rotors drilled or slotted?
A: Rotors are drilled to reduce rotating weight, an issue near and dear to
racers searching for ways to minimize unsprung weight. Drilling diminishes
a rotor's durability and cooling capacity.
Slots or grooves in rotor faces are partly a carryover from the days of
asbestos pads. Asbestos and other organic pads were prone to "glazing" and
the slots tended to help "scrape or de-glaze" them. Drilling and slotting
rotors has become popular in street applications for their pure aesthetic
value. Wilwood has a large selection of drilled and slotted rotors for a
wide range of applications."

ive heard that x-drilled are pretty much for show coz under heavy use cracks can develop from hole to hole.
