How much do Crossdrilled & Slotted Rotors go for on our cars? Also how much are stock rotors?

I know people who have a machine shop, and am wondering how much it would be to have them make them. I know the've done some brake stuff for hondas.

Got my dimpled and slotted rotors from Shark Racing, with Hawk pads for 200 bucks. They work extremely well! Huge improvement over stock rotors.

How much do stock rotors cost?

Do '04s use the same ones as 01-03?

I just ordered these bad boys

Should they come in with little duty applied I should get them for alot cheaper than stockers :)

Do not have your frinds drill blanks. The could very easily hit a vein and cause a tiny little stress crack that can not be seen but will cause the rotor to crack while braking.

I have the KVR rotors and KVR carbon fiber pads and love them.

Those are pretty much the same ones I have, and I love em.

Make sure when you buy a set of performance rotors that you get a set that have been cast with the holes and slots in them. The problem with the ones that are actually drilled and then milled is, when they do this, it weakens the rotors. I know that Raybestos, Baer, and the BIG companies actually cast the rotor with the holes and slots in them. Check them out before ordering them...

I have heard on here that '04 have captive rotors, how much harder does that make them to change?

The 04 does not have captive rotors. The ones with captive rotors are i think halfway through the 99 or 98 year model and before.

Oh, I though they were talking about '04s.

No one has answered as to wheather '04 uses the same rotors as 01-03. A lot of places do not have 04 listed yet.

To add to what 04 elantra cvvt said, just because it is a big name doesn't mean they were not drilled after casting. Companies out there will buy Brembo blanks and improperly drill them and resell them as Brembos. Mistakes can be easily avoided in purchasing such rotors by asking a few simple questions such as does that company make drilled rotors for my car and is the company I am buying them from an authorized distributor.

Hyundai stopped using captive rotors in mid '99 and nothing from 2000 on had them. I also highlly doubt anything Hyundai puts out ever again will have them since they are a service nightmare.

Its the same bolt pattern so you should be able to use them no problem.

Autobot, that is very true. You still need to ask questions. And jameswing, according to my local dealer, yes, they are the same. As are the pads.

Have you installed these yet? If so how do they perform?

Yea, same question Carbon???

I sent an email to that company Carbon got his from in the link, and asked if they were made with the holes and slots in them, or if they were machined from blanks. Here is their reply:

These rotors are manufactured OEM, meaning they do not come cross drilled. We get your exisiting OEM specification rotors and CNC machine them, and silver zinc plate the rotors to make them more durable. If you have any further questions please feel free to ask.

No I haven't even received them yet, they only shipped them 9 days after I paid/won the auction

That sucks, I have had people wait like that before. I saw an auction and the guy said he only shipped items on the 1st & 15th of the month to make it eaiser for him.

don't get cross drilled and slotted, cross drilling cools the rotors down and reduces brake fade, slotted rotors heats up the pads and "shaves" the pads making them melt on the rotor. slotted rotors are primarily used for racing. having both applications defeats the purpose of having slotted or cross drilled since they counter act each other. stock rotors are $80.00 cad at the delearship. go w/kvr's. www.kvrperformance.com they work great.

One of the purposes of the slots is to sweep the dust away from the surface of the pads. They don't shave the pads down. I ran them for a long time and the pads actually lasted longer that with the stock rotors. The cross drilled and slotted rotors actully complement each other.

Huh? Maybe if the slots and holes were not chamferd, But even then everything wears smooth.

Holes allow the disk to cool faster and slotting allows the gases that build between the pad and the rotor surface to escape. It does seem like over-kill to have both.

I have drilled and slotted rotors that were done from blanks. I bought them off JPJR and I can't remember where he said he got them from tho... it was off Ebay. I would rather have just slotted rotors but JPJR made me an offer I couldn't refuse.

By the way, I drive the **** out of them including autox so if there is going to be a problem, I'm sure I will find out.

Also, can you have them resurfaced?

cross-drilling and slotting aren't needed, the width of the rotor and efficiency of the cooling vanes are what make a rotor more effective. In fact, F1 cars have neither cross-drilling or slotting, the brakes are relatively small in overall diameter too, they are just really thick with great venting. The owner of Williams Performance Friction made a presentation at our Motorsports Club meeting and here's a synapsis of what he said:
What was clear from Bill’s presentation is that the chemistry and physics of brake
pads are very complicated, and that lab testing is no substitute for real-world testing.
Interestingly, Bill advised that modern pad materials do not generate gases at high
temperature and so drilling and slotting of rotors serves no functional purpose and
are often detrimental to brake life. Also, he advised that a performance pad is good
until the friction material is all but gone, and since it is fully cured during
manufacture its braking performance is consistent throughout its life. Another
interesting suggestion was that the benefits of 600 degree racing brake fluid are
negligible over Ford 550 degree fluid which is widely available at a fraction of the
price.

Yes, they can be resurfaced. We do quite a few of them. They just make a funny noise on the machine, but other than that, everything is normal.

Cool, thanx. I was wondering about having them re chamfered too. I can do that myself on my drill press but is it needed or worth it?

I wouldn't worry about it. It would just weaken the material around the area that you are messing with. The area is still flat so there is no need to worry about a cheese grater effect.

well I received the rotors yesterday, they look great, however being involved in the steel industry I know that these rotors are NOT zinc plated. They will still last a long time though and are high quality. I'll just have to add a coat of paint to the non-wear areas

when do you think you'll get them installed

shoot, who knows. I have alot of stuff still to be installed

Probably in a week or two, I should have all open jobs done by then. Then its my cars turn to get further tricked out
