I know an old racer who did testing on this back in the day when he was racing. He said that they found out that the drum couldn't hold up and all the test drums at the end of the day where cracked and some even exploded while braking. Now this was for racing use which demands more than normal daily driving and this was also many yrs ago(70's or 80's) It is possible that they drilled too many holes or made the holes too big or that the material used for drums then was lower quality. So it might work well now when/if done right. I would just keep a very close eye on them and see how they hold up. I have passed on the opportunities to drill my drums because my thoughts are that if it really did work we'd see ALOT more people using them by now. But you dont hear about people running drilled drums and its not a new theory...
