the drilling and slotting make the rotors look great, but do not solve the main problem-
imo, the rotors are the weakest design flaw of our cars... they look horrible on the car- rust no matter how the car is cared for. i will never forget the first car i saw in late '99- great looking car in all respects... but, wait- whats with those rotors? cant afford to put a rotor on the car without rust???
cad plating is one solution that helps alot.
i put on drilled and slotted cad plated rotors- didnt want more dust, so i installed them backwards so the slots dont really do much other than look great!
and you are right on- dont drill or slot rotors on a track car.... cause you want track rotors as strong as possible, and drilling or slotting will weaken the rotor material.
just my opinion, but i think that these fit our cars much better than the stockers...
is there a cad plated and slotted rotor thats just a little more than oem rotors would be or are they all about 2, $300 more? or am I just lookin in all the wrong places? lol
Edit: ones that offer just as good quality/breaking heat resistance as OEM
Anyone else think that a job in the "friction industry" sounds a little suspicious.? For example, "I was working at the friction factory with your momma last night!"
rotors like brembos have holes already planned before they cast them, that's why it's so expensive, because there are more labor involved in it to clean it up. However, the benefit is that the rotors will be much stronger since the molecules are evently distributed around the integrated holes, which means no cracking.
It's not the crystalline structure around the holes that makes the rotor less prone to cracking. It's stress risers set up in the drilling process. BTW, the Brembo rotors also crack around the holes. Get them hot on the track and they crack. I've trashed many Porsche rotors in the past with 'cast' holes. I prefer slots.
Cad plating is a surface treatment. It will good for the long term on the hat but will wear away on the rotor surface.

Not at all. And he's right, unless you have an understanding of machining and metallurgy, you are best not to screw with trying to drill or slot your own rotors.
