drilled slotted rotors?

deadlast · Sep 23, 2005

i was browsing ebay when i stumbled upon brake rotors. i found many cheap cross drilled rotors, but found 2 front and 2 rear drilled and slotted rotors from brembo. same saize as stock, so they should bolt right up, but im wondering if its worth it? how much of a braking improvement could i feel?

HUH? I'll let you know as soon as I put mine on. Not Brembro but same rotors. As to the seller though, anyone with less than a 99% positive rating and not a powerseller doesn't get my business. As a result, I have never been burned on Ebay. That guy has a 95% positive rating which means he has a lot of unsatisfied customers.

Pokageek you do realize that 95% is a excellent rating for EVERYTHING ? People do make mistakes.

1038 positive
45 negative..

I would still do business with him.. But check his feedback.. Some say they are not "Brembo as advertised."

Everything? I have to disagree with you on that. How about having 95% of your body parts?income? health? phone minutes?

If I have 95% uptime on a computer network, I get fired.

In relation to ebay, that's just not good enough for me. I respect your opinion on that issue but I am not changing my position on it. It may be conservative but I don't care, I haven't lost money so far like a lot of others. This guy has a lot of hits on poor service, shippments over 1 month in delay and problems with fittment and quality.

p.s. just to show you I practice what I preach here is where I bought my rotors..http://cgi.ebay.com/ebaymotors/FORD...ewItemQQcategoryZ33564QQitemZ7998900326QQrdZ1

After a lot of research, I discovered the only cross drilled slotted rotors to get are Wilwood, and Brembo.

Reason being is, they are not actually drilled. They come out of the mold with the holes already in them. This makes them stronger than most cross drilled rotors that are drilled after they are made. Drilling after makes them weaker and more likely to crack.

After speaking with a couple guys who race at Dave Turner Motorsports, and a few others at JBA, they all seem to agree that coatings are useless. They will be burned off in the first major heat cycle, and can cause premature brake pad failure.

The best thing to do IMO is get a nice set of rotors, and a great set of pads. If you really want a lot of good info on brakes, call John at Dave Turner Motorsports in San Diego. He will set you right.

I just got the slotted rotors. I upgraded the front to cobra's and put hawk pads on the stock gt rear's. Now I get whiplash when I jam the brakes. Ther's no nose dive though!! I have a spare pair of slotted/drilled rotors with the zink coating if anyone looking for some.

What's your ebay rating? LOL, just kiding!

I've used powerslot rotors for years and didn't see any cracks. Stop much better than stock.

"Ther's no nose dive though!! "

I have heard this is a big plus to getting Cobras! I don't think I am going to get that with just slotted and drilled.

Dont purchase drilled rotors they will crack in a very short time. Mine was junk in 30 days and was a brand name product. Only purchase slotted. Another negitive is you can't have them turned.

Do you auto-cross? What are your driving habits? What brand? Thanks.

p.s. Mine are warrated for 90 days I think but yes it would be a PIA if that happened!

I have to ask but what brand, because really i've had rotors off ebay from "hitech rotors" on my rears for over a month and they are still in mint shape. were you road racing beating on the brakes? possibly wash the car while the brakes were still hot warping the rotors, causing them to crack

"Another negitive is you can't have them turned"

Cross drilled slotted rotors stay so much cooler that you wouldn't really need to have the rotors cut, because they are so hard to warp, as long as you stay up with pads your cross drilled rotors you should be fine,.

This probably won't go over well, but, I bought my cross drilled and slotted (cheapos) from JC Whitney in the fall of 2001. Been on car ever since. Went autocrossing once when I first got them for two days. Instructor that rode w/me said the only thing my car was lacking was tires and more seat time for the driver. I just started noticing wheel vibration under braking about a month ago. Unbelievable, but true....

I bought my set on e-bay for like 120 bucks, 2 fronts and 2 rears. The seller was great ordered them on a monday and they were at my door by friday..
