Cross-Drilled Slotted VS Cross-Drilled
 

which works better or are they same? currently i have 4 Cross-Drilled rotors and i just got new brake pads so i'm thinking about geting CD-slotted rotors for the front.

thanks guys:)

Im not sure about the crossdrilled and slotted but I have heard that cross-drilled are more likely to stress crack than slotted. Someone confirm this for me.

Heard the same. Alot of road racers like the blanks/stocks, or the slotted with a good set of pads.

I heard that if you cryogen "freeze" the cross drilled then it shoulded crack under stress, if your rich go for it, Im not so Im going slotted.

True:)

Fricken waste of time to drill rotors...

Not to name drop, but BREMBO (NA) Chief Engineer designed his/my (track centric) FD with slotted rotor all around. Get the feeling his design choice speaks for itself! :beer:

a lot of racers like blanks since they know cross drilled is just for show!

Carlos, your car is awesome. Nice write up in RX Mag. Yea, I noticed the rotors were slotted. Your CYM must be a blast on the track.:)

cpa7man, Thanks for the respects! Unfortunately, haven't had all that much of a chance to really shake it down due to my heavy cruise schedule this year. There's always next year. ;)

Back to the topic at hand, I fully appreciate the aesthetic appeal of cross drilled rotors. I've also often wonder why an OEM manufacturer with a legacy of braking prowess such as Porsche still uses cross drill rotors in their cars? I hope against hope that it's not just for the looks... perhaps I'm still naive.

That said, I'm sticking to slots and solids.
