Drilled/Slotted/Dimpled?!

[speedminded]

Yes and No. Like you said, old pad compounds gassed and original cross-drilling reduced that effect. These days, many of the larger high-performance rotors are drilled to help reduce weight and to help with wet braking.

I think I can understand the explanation of heating up fasterand more heat dissipation. I conclude that he means that the rotors will warm up faster due to the reduced mass, and because of that reduced mass, they cool down faster (with proper ventilation of course). Is this true? I dunno, but in theory it seems to have merrit.

Yes they would get up to operating temperature faster but they would also operate at a hotter temperature because it's reduced mass is doing the same work as a blank would.

There is a quote somewhere from the current or past Brembo president stating that cross drilled rotors is a cosmetic feature and does not offer better performance, it's only lighter.

but yet, along with the less weight part arnt pro racers always lookinf for ways to "reduce weight"???

Show me a single RACE CAR with cross-drilled rotors.


Let's start with F1.








Nope.



How about C6R brakes?



Nope, but if you're lucky you might see steel rotors with j-hook grooves...




How about Flying Lizard's 997RSR ALMS car?



File 404 Error. Cross-drilled rotors not found...





How about a ALMS e92 M3?






Cross-drilled rotors are a JOKE. It's purely a marketing scheme and nothing else.

Stock e92 M3 "performance" brakes vs. AP Racing BBK.

Want to lose weight? Get a real caliper. Non-drilled rotors and still 10lbs lighter

blah blah blah blah blah
some cool pics

lulz. u took the bait.

anyways i got powerslot rotors
