Once again I have to respectfully disagree with Dave on this one too. I have never had a problem at all using a drilled rotor, so long as they were rotors with the holes cast into them. Personally, I have used slotted and drilled totally interchangeably on our race cars and on my street cars, and have not once run into an issue. I could see how an imporperly drilled rotor could introduce problems, but no more so than a cheap replacement rotor, or cheaoly done slotted rotors.
Actually, both Brembo and StopTech engineers have observed, during testing and racing, that the behavior of drilled versus cast holes is very similar. Brembo even put something up on their website about it: http://brembo.com/hp_faq.htm#22

This is consistant with what I've seen on customer cars. The folks who race hard (and I mean good drivers in advanced run groups with R-Compound tires) will often end up having to replace their rotors because the micro-cracks start to expand BEFORE the rotors reach their minimum allowable wear thickness. The slotted and plain rotors last longer, on average, than the drilled because the drilled crack sooner and open up sooner. (None of this is meant to imply that Adam is anything less than an expert driver, nor to dispute his personal observations. I'm just providing additional data from multiple sources.)

For normal track-day users in novice and intermediate run groups (especially with street tires) or for street-only drivers, I don't see drilled rotors as a problem. My earlier comment was that drilled are not appropriate under "race conditions".

However, there are lots of drilled Brembo rotors on eBay that were not drilled by Brembo. They were plain rotors purchased in bulk and machined by someone who did not know what they were doing. The holes are often carelessly positioned and often too big. I would not put these on any street car. If you plan to get Brembo drilled rotors, get them from an authorized dealer, such as Tire Rack or Z1 Performance.

Dave - good post man, thanks. I think the difference we may have seen is on the tracks we tend to run (Northeast) we just don't use much brake ....slows you down too much

The point on the R compounds and in the upper classes is a very important one to consider as well
