He simply asked about cross-drilled rotors. Why is it so hard for some prople to accept that without crying slotted rotors? I understand that slotted rotors are better, but cross drilled rotors aren't going to make his car explode into flaming hunks of GXP.

They very well could. I see it happening to the ricer crowd more and more often around here. Drilled rotors are a very popular rice thing. Not only that, but they're throwaways instead of turning them. And they decrease braking performance. I assume he wanted performance, or he would have posted this in Detailing and Appearance.

I have a very close relationship with one of the best Custom Shops on the East Coast and they sponsor my car to the tune of several thousand dollars and can positively say cross drilled rotors can be a hazard. So maybe not everyones break apart and not even a majority, But, they do fly apart and I've seen 2 at the shop. One did extensive damage to a RX-7 with a very expensive front body kit. He'* lucky it just cost him some fiberglass because this turboed wankel develops monster boost and does well over 200.

I realy like the look of the cross drilled but after I inquired and was shown what can happen, I changed my mind. Daytona, Will Wren is one of the most knowledgable all around mechanical persons i've met in forums and devotes alot of time to performance mods and research. He speaks from a large database of info and for his position here(rightfully given), he is a very level headed man. I have even clashed with him myself and found him to go out of his way to meet me more than halfway. Ok so you like the look, maybe even judge them better. But this is a forum and is about evaluting all the pro'*, cons, and opinions available.

I have learned that my mood and how I interpet things can change how I take something i've read. I hope you guys have talked and things cooled off. I'm not taking sides on your collective dispite, but relating what I've seen . I dont feel Capitalizing 3 words makes for abusive power, rather his worry about this issue and i'm sure you just read it stronger than it was intended. If you feel the cross drilled are for you and they worked well on another car you have fine but everone here has a right to their oponion.

One of the best local shops for brakes is developing quite the collection of cracked and shattered drilled rotors. People don't seem to understand that F1, IRL, and NASCAR throw rotors away after every race.

Cars like the 'Vette that get them OEM from the factory use rotors with the holes pre-cast into the blanks before hardening and final machining. But the rotors are also larger in diameter to make up for the loss of braking surface area from the holes.

Yes, I've done alot of research myself. Partly for myself, partly to clear some things up here. This goes back over 3 years because of a member that joined making some interesting claims. It started here:

This is the beginning of our quest to answer the drilled rotors question once and for all.

For anyone thinking about doing this, I suggest you do your own research. Don't rely on the information I posted above. Do your own search and convince yourself. There simply is no good reason to go with drilled rotors other than cosmetic. Sure, they look cool, but then agian, the more the ricer crowd gravitates to them, the less cool they look every day. That'* just fine. Import tuners can have the brake failures and decreased braking performance, while I use quality components on my own car.

Will, don't get me wrong, I really appreciate all the research you've done on brakes. I would never use cross-drilled rotors on MY car because of your work, and would just stick with slotted or solid rotors.

If he wants cross drilled rotors despite the facts, let him go. That'* all I'm saying.

I agree completely. It'* his car. I personally will not take chances on the brakes and tires. I've found slotted rotors to work very well for me, paticularly with the good amount of rain we get here. But if slotted rotors weren't available, I would NOT go with drilled. Not with what I know about brakes.

I think it'* clear that this is simply a cosmetic mod, not performance. And that there is some apparent risk. You just have to decide for yourself if the risk is worth the 'look'.

The topic author also needs to understand that if he asks a question like this, we're going to tell him what we know. Maybe more information than he was initially looking for, but that'* what this Forum is about.

If someone posted "which eBay $50 performance chip should I buy?", we're not going to tell him the cheapest one. We're going to tell him about the myth.

I have drilled/slotted rotors from napa and Hawk pads and these are the best feeling brakes ive ever had.
I dunno but these cost a buttload and napa stock quality parts.
4 months no warping even after several 100+ mph stops in a row no fade either

And you have less braking potential than you would if they weren't drilled. You're missing surface area. You should have increased your rotor diameter by the area of the combined holes.

I hope those holes were cast into the blanks and not drilled. The potential issues you may have in the future have been very well covered in this topic, and it would be pointless to re-hash them now.
