Drilled IS a novelty. Ask anyone who actually tracks their car. Also look at actual race cars with iron brakes, you won't find holes.

The holes create an area of uneven heating which eventually cracks during racing. Drilled rotors are thrown in the trash by guys who use their cars hard.

Also, in the examples you listed, many of those cars are only available with carbon/carbon brakes. That is an entirely different ballgame from iron rotors. If they do feature holes, they are cast into the rotor, not drilled, and they are aesthetic because 90% of their customers will never use the car the way it was intended.

Here are multiple MAJOR performance brake manufacturers who DO NOT even make drilled rotors, and actually advise against it....

I remember when they did try drilled rotors on heavy race cars = exploding rotors. Drilled rotors work fine on motorcycle but not heavy car

And there are multiple MAJOR performance brake manufacturers who DO make drilled rotors.

GT350 and GT350R...both come with drilled rotors (and we know for sure the R is designed for track use)
Corvette Z06...drilled rotors (also a track-prepped car)
Nearly every Lambo, Ferrari, Bugatti, (insert super-car) and most still come with iron disc brakes...

But what do I know...I'm not a vehicle or brake engineer so all these manufacturers must be idiots....

so lets ask the experts here.... the GT35R rotors are only drilled and NOT slotted? so what's right, what's wrong? What functions and what doesn't? why would engineering Idiots at Ford and the rest use a drilled rotor for track?? All you racers say you wont find then at the track?????? :confused::confused::confused: Definitely look better though! I might just have to get a set!!! :cheers:

Porsche gt3 has drilled two piece. Anyone who tracks them knows they will Crack. It's just another maintenance thing. Cheaper than carbon ceramic disks.
