Natanko to sem mislil, da namreč torni količnik ostane praktično nespremenjen, tiste luknje imajo pa eno samo funkcijo, in to je odvajanje tistega plina, ki nastane pri pregretju ploščic. Ker v bistvu luknjasti diski niso sicer v ničemer boljši od običajnih, kvečjemu bodo strojniki povedali, da zaradi povrtavanja postanejo bolj krhki. Zato pa so pri športnih avtomobilih tako predimenzionirani, da se te pomanjkljivosti skompenzirajo.

strokovnjaki pa bi povedali, da se ne vrta lukenj v diske, ampak je disk že tako ulit

zareze na disku pomagajo čistiti, luknje pa pomagajo hladiti disk.

An important note about drilled rotors:
Drilled rotors are typically only found (and to be used on) race cars. The drilling weakens the rotors and typically results in microfractures to the rotor. On race cars this isn't a problem - the brakes are changed after each race or weekend. But on a road car, this can eventually lead to brake rotor failure - not what you want. I only mention this because of a lot of performance suppliers will supply you with drilled rotors for street cars without mentioning this little fact.
