Drilled Slotted Rotors

RE: Drilled Slotted Rotors
I've seen a guy on ebay selling pads, and drilled/slotted rotors for the H3, with incredible feedback, and people noting they were repeat customers.
If it wasn't for that, I would say stay away from anything drilled. For the most part, companies make standard width rotors, then drill them, which causes them to be very weak, and crack.
You may say that you have seen drilled rotors come stock on certain cars, exotics mainly, but this is becaue they increase the width of the rotor, adding the neccessary strength for drilling.

RE: Drilled Slotted Rotors
DVader is 100% correct - drilled rotors are for looks only - loss of metal = loss of surface area and decreased heat transfer = loss of stopping power.
Slotted rotors - depends upon the location, number and direction of slots. For frequent stops from high speed (180mph- - >40mph) where gassing might cause pad float, properly slotted rotors allow gas to escape and more immediate friction to be applied. In any other situation, slots =less surface area=less stopping power. Unless with the change in rotors comes increased diameter and that increase equals or exceeds the loss of surface area from the slots or holes compared to stock, it is always a losing proposition.
