Well I really needs some rotors for my car and I came across this on ebay

http://cgi.ebay.com/ebaymotors/_Car-...1%7C240%3A1318

You guys think its a good deal???

 

They actually look half decent. I'd look and makes sure that the diameter matches the stock rotors (I didn't check) and I would worry that some cheaper sets of rotors may rust around the outer edge from my experience with my 300ZX. They say that they have an anti rust coating but this doesn't always work as advertised.

 

I'd worry more about the cheap, drilled rotors cracking, along with the quality of the brake pads...

 

I'd use different name brand pads entirely but the rotors can't be terrible especially for conventional street driving. If anyone has first hand experience please feel free to chime in because my guess is well...just a guess.

 

Im going to give you totally different advice from the last post. The Posi-quiet brake pads are actually pretty decent. I have them on my G. Very little dusting, no brake in time, but you do sacrifice a little performance. Perfect for the street, not the track. You gotta sacrifice either dust or performance.

The drilled rotors I would stay away from. Ask them to give you plain rotors, or just slotted. These ebay stores do not drill the rotors properly. At first they will be fine, but they will defiantly crack with some solid spirited driving. And god do they make some annoying noises while braking. (i bought some ebay drilled amd slotted rotors for my old Grand Prix and I would not do it again)

 

eeek. Honestly... seems like a great deal but for some reason pairing ebay and brakes for my car don't mix very well.

 

brakes and tires are the 2 most important components of safety on a car... i wouldnt risk buying ebay rotors/pads unless they were name brand.

Do yourself a favor and hit up Riverside infiniti, they can get you the best pricing on OEM parts.
-GP-

 

Atleast try to go with a name brand rotor!!!. I have those brakes and they are good....Nice and quiet and no brake dust...

 

my personal rule of thumb, if the part moves dont buy it from ebay.......

 

I wouldn't put them on my car.

Yes they look damn good, but i would crack those babies in one session of autoX.

Best rotors IMHO are OEM, or Quality blank rotors like Brembo or Baer. I would even trust Brembo or Baer's drilled rotors if i wanted to go for that look (which i do since I'm going for more of a show theme with my G rather than race)

Where I autoX, they wouldn't even let you race with rotors like that. Their process for drilling the rotors is not the same as how Porsche or Corvette creates the driled holes in their rotors

 

I would never buy cheap brakes for my car. Too much to go wrong. IMO you get what you pay for with brakes. Spend a little more and get something proven.

 

OEM pad/rotors are the best way to go... yes its more expencive but id rather have quality parts then cheap unsafe parts

 

Okay heres the thing. Cross drilled is better than slotted for normal driving. Everyone that knows racing knows that. Heres why;

Slotted rotors are intended for "shaving" off the glazing that happens during frequent high speed braking. If you use them on a normal car, your pads will disappear in no time, with little to no functionality.

Cross-drilled allows for the gasses and heat created to escahpay (escape), and under normal driving conditions this is good, it increases stopping power and doesnt shave the pads down. Also cross drilled helps prevent water on from standing the rotors, like if you drive through a puddle or its raining.

I would definitely use a trusted brand, since it is the MOST VITAL part of your vehicle. You can get some power stop cross drilled from Summit Racing for $330! Which is only a few bucks more and certified performance.

As for the sound that they make mentioned earlier, its actually hard to describe but if you watch my "LEXUS IS 300 Performance Test" Video on YouTube, you can hear it when I approach the camera slowing down at about 2:12 in the video, but watch the whole thing because im awesome and you love me. Thanks!

I disagree. Crossdrilled rotors on most cars is for appearance only.



First off, $200 ebay crossdrilled rotors are nothing like Porsche crossdrilled rotors. They are designed and cast with the holes in them. Most aftermarker rotors are drilled after being cast and non-chamfered, which increases stresses.

Second, modern street car pads don't gas. They did in the 1960's, but today they are gas free. So there is nothing to vent. Exotic race cars with racing pads do gas, but these are your porsche and lambos which i told you are not the same as $200 ebay rotors

third, cooling. The drilled holes are perpendicular to the airstream. If you did a study, you'd find virtually ZERO airflow goes through these holes. Rotors are cooled centrifigally with internal vanes like a pump. Air is drawn from the center and flung outwards. In order to pass through the crossdrilled holes, the air would need to stop and travel 90* to the direction it's being flung. Not going to happen. Rotors also get their cooling from their mass. HEavy massive rotors cool much better than lighter rotors because the heat is dispersed evenly. When you drill rotors, you reduce their overall mass, so the heat from braking has less metal to travel into resulting in higher rotor temps and can lead to "warping" or cracking.

Slotted rotors do "wipe" the pads surface and can increase wear, so they do have a minor benefit. I particular don't feel they are worth it, but they have been shown to do "something"

So long story short, unless you are running exotic brakes with pads that release gases, crossdrilling does nothing for you. It's purely cosmetic. For performance, your best rotor is a boring, dull plain faced solid rotor.


I know a lot of people will say they put these $200 crossdrilled rotors on and it helped, but lets be serious. Most of them are taking off stock OEM 40,000 mile worn brakes. You could go to autozone and buy $10 rotors and pads and your initial impression will be an improvement. I know because i've done it. NEW brakes always feel better than worn stuff. It's when you push the brakes in racing-type applications that you find out their true quality. You get what you pay for.
