The cross-drilling, is worth more than poseur points; it actually helps the brakes work better. Under hard braking, a brake pad's bonding agents burn off and produce gases. Cross-drilled holes allow those gases to vent, helping to prevent brake fade. Also, when water contaminates the rotor's surface, the holes allow moisture and muck out rather than causing the pad to "float" over the surface of the rotor. Cross-drilling also improves rotor cooling, again defeating brake fade. On cross-drilled rotors, temperatures can be reduced by as much as 200 degrees during extreme braking when compared to stock rotors. Since braking is essentially the absorption of a moving vehicle's kinetic energy and conversion into heat, rotors that quickly and efficiently dissipate heat perform better. Cross-drilled rotors increase rate of heat dissipation by decreasing surface area, allowing gases to escape, and increasing air flow.
