Why use drilled or slotted discs?
Drilling or slotting discs aids the disc in several ways:
The edges of the slots or holes continuously clean and refresh the pad surface as well as providing increased brake "bite". Additionally, they prevent gasses from collecting between the pad and disc interface.
The disc is lightened, thereby decreasing its rotational inertia.
Improved ventilation increases the disc's ability to shed heat, resulting in cooler operating temperatures
IMO I used OEM and brembo rotors (which i currently use)
the brembo have lasted much longer than the OEM rotor (which i replaced because they warped at 12,000 miles) so far i have put 28,000 miles on my brembos and they barely have any warping.
people say dimple drilling is better because it "does the same thing as drilling but does not affect the integrity of the rotor." As the pads closes on rotor, a drilled hole would let the rotor and pad contact as better opposed to a dimple drilled rotor.. my reasoning? as the pad closes in on the dimple, it can create an air pocket in that area, which could be slightly pressurized, going against the force of the pad. Also holes are meant to "shave" a layer of the pad giving some fresher unglazed surfaces of the pad to brake with. The residue would flow out of the hole in a drilld rootr.. what about dimple drilled?
as far as drilled rotors cracking, I never "broke in" my brembo rotors, even by stupidity ran my pads down to the metal and braked with them, and they have not cracked nor has the surface been fuct up

would you all recommend replacing the pads as well.
thanx for all the info and opinions...

As I said nowadays cross drillled rotors are a waste on CARS. Pads don't gas as much and hit hurts the intergrity of the rotor UNLESS the holes are CAST into the rotors. Ever see a rotor shatter while on track? It's not nice.

I have the Brembo OEM cross-drilled on my front right now, no problems. I also got new pads, they aren't fully metallic so they don't squeel or need to be 'warmed up'. They aren't dustless, but they are significantly less than standard pads. I don't know if Hawk makes pads for Honda's, but my friend's E46 uses them and they are great.... on a similar note, I think I'm going to go for the Brembo Gran Turismo Big Brake Kit very soon....anyone try this on their car yet?
