Ok, i have read 1,000's of threads, posts, reviews, and tech articles...Even though i have found ZERO brake dyno or any other physical testing information as a whole it appears cross drilled brakes are purely cosmetic and only used as a hoax for the increased sales of higher end sports cars and more expensive "upgraded" brake systems.

Nearly every single company mentioned above that claimed that cross drilling offers no advantages does in fact claim somewhere that they operate cooler...from Power Slot to Brembo to AP Racing. Is it a scam? What's the deal? who knows?
