i have heard very bad things about cross drilled rotors (especially the brembo ones). They are truly drilled instead of CAST which means there are microscopic stress cracks which can ultimately lead to a cracked rotor (VERY BAD). so be careful. just getting better brake pads would probably yeild better braking.

How do you think they make them? HINT: The name gives it away!

Cheap cross drilled rotors do not have chamfered or radiused (better) holes that limit or eliminate stress cracking.

NO THAT IS NOT WHAT IM SAYING, you dont know what u are talking about....

TRUE BREMBO cross drilled rotors are not DRILLED at all. they are CAST that way in one solid cast. anyone who knows anything about brakes knows that. Those on ebay are just brembo blanks drilled thats why they are dangerous. All OEM X-drilled rotors are CAST, those found on porsches, ferraris and benz and etc are all CAST cross drilled to ensure there are no stress cracks and etc. If you dont konw what u are saying don't comment.

Put down the crack pipe and calm down man.

First off, I know plenty about brakes. This is an old topic that has been beat to death many times in many forums . The holes in almost all Brembo aftermarket rotors are cross drilled, not cast in. Yes, most high dollar OEM applications that use Brembo have the holes cast into them before machining but not all OEMs use cast holes. The cost to cast them in before machining is huge and because of this almost no aftermarket rotors are cast this way. Anyone who knows anything about brakes knows that.

...and BTW, try reading what Brembo has to say on the subject.

Their site is not very friendly but here is a link to their FAQ on another site.

Personally, I think the answer they provide applies only to rotors drilled by Brembo or to their specs and not by someone else using poor techniques.

Regardless, cracking of OEM Porsche cross-drilled rotors is a normal occurrence. Porsche owners recommend replacing the cracked rotors when the cracks near the edge of the rotor.
