who has tried ebays cheap rotors?

[dsm03]

Unless they are a reputable brand like Brembo, Stop Tech, Wilwood, etc..

You re better off going with blank rotors from like autozone or your local autoparts store.

I've had my Dsm for over 13 years and have warped every set of oem rotors. Until I went with a set of drilled and slotted rotors and yes off eBay. Just happen to be a guy I know in Chicago though. When I get home I'll post the link. Have to say the very best rotors I've ever had on my car. They even came zinc dipped to fight rust, and I will tell you it works. They also came with ceramic pads. I've been running them for about 2 years now and still have like 80% pad life, and I drag race once a month. I also daily drive my car about 50-60 miles a day and that's alot for this small island . The main problem with oem rotors is the center section will rust and fill up very fast. What happens is the center fills up and blocks the fins from being able to vent and cool the rotors properly. This is why in my opinion a zinc dipped drilled and slotted rotor is a must on dsm's. If you don't believe me I can post a pick of my setup. I live in Hawaii where the salt air kills everything in it's path. My rotors still look fairly new.

Ok so the ebay store is called brakemotive and here is the link. Brakemotive items - Get great deals on items on eBay Stores!, check them out. You may have to look under eagle talon for some reason, when I just looked no eclipse came up. Or just give them an email they have fair prices and a darn good product, I got my rotors with the evolution pads. Great combo deal.

+1. I've ran the same zinc rotors from that vendor for over 2 years. I have never had any issues stopping. Not even at 150mph.

I ran Rotorpros front slotted/drilled front rotors on my Sentra for 5 years/7 sets of pads. NO cracks, warping, anything. they just got so thin (the slots where gone) that I had to scrap them. I use to AutoX this car too.

$117 shipped with Ceramic pads.

 

[cwriley]

relieving heat incurred internal stresses will cause a condition where the rotors are more prone to failure than if you had left them alone in the first place. Do not turn rotors, get rotors with a replacement warranty and just replace them if you need to

yes if you turn the rotors too deep it will diminish the integrity of the rotor but there is a minimum refinish spec. as long as you don't cut the rotor too thin its fine to cut. stops better even. after time rotors get hot and warp (lateral run out). if your using cheap 20$ rotors ya replace them but if you have a good rotor you can cut them.

 

[KeelesKustome]

I gave $220 for my drilled rotors and pads, off ebay, the quilty was top notch, and I have been a DD with this for going on 6 months with no issue, other than i need new pads now, as the drilled rotors eat the pads pretty quickly.

I didn't go with the cheapest on ebay, and I didn't go with the most expensive either.
It seems to me the rotors are as good as any aftermarket rotor, and they just tapped into them with holes to let them cool better.

You all realize that:
1. Ebay still doesn't make any parts
2. "Drilled" rotors is a misnomer in and of itself. The "drilled" bits are cast/molded.

Don't do "drilled". Do slotted only if you must. Blanks are fine for 95% of folks on this site. (a guess, but likely close)

Why you need some fashion accessory brakes that likely have piss poor QC on a 14 second car...hell if I know.

The next thing you know, someone will ask about carbon brakes for an NT....wait...

I was going to comment on this same thing. Porsche/Lamborgini/Audi, etc. cast the holes into their rotors. You can't compare it to the junk sold on ebay. Porsche has a QA department that ensures all parts are to spec. The guy in china could care less if you die.

I've once been told that some companies buy Brembo blanks and drill them. So I could imagine the cheap china rotors being cheap china rotors and drilling those too.

In the case of eBay, I do not think that "drilled" is a misnomer. REAL, quality rotors from reputable manufacturers is one thing. But cheapo blanks with a 15min CNC/CAD drawing and a drill bit is a different story.

I also think it's quite clear to (hopefully) most of us that eBay does not in fact produce parts. I mean, well I'm not going to say anything else about that cause its just effing retarded. What's the problem with grouping together cheap/no name parts that are pretty much only available through eBay, and calling them eBay parts?

I'm praying someone doesn't drag this out into a generalizing/stereotyping issue..oh wait..

Seriously though, good shit on the CF brake thread. haha!

 

[pbwu1f]

I think you should save up and get good rotors. If it's a must to get the car running just get some from the auto parts. I hear to many stories of these cheap rotor exploding and causing people to crash.

It's pretty much $30-$40 for any Centric branded rotor. Fantastic deal.

 

[laserspeeddemon]

I just don't understand people's thought processes. I've seen people LITERALLY dump over $1000 on a brake setup. It would be MUCH more cost effective to get a Cobra Setup.

Thats some nice brake set up. Wouldyou mind telling us where you could get them from??

Well I have been using some zinc dipped drilled and slotted rotor in the fron't and back for 3 plus years on my DD and the rotors still look flawless and it definetly improved braking power for me.

I bought them from a local company called Rotor Works. And by the way, they do all of their work inhouse.

 

[dsmfa9nutter]

Stay away from the drilled rotors. Just imagine some chinese kid working a drill press drilling the holes and then throwing them in a box going straight to your door. There is a reason they are cheap and plentiful. Slotted are ok but are really for show, nothing more. Vented rotors are perfect. The thicker the rotor the better.

 

[Todd TCE]

Porsche/Lamborgini/Audi, etc. cast the holes into their rotors.

You have any solid proof to back up that statement?

I (and others) have well over $500 for anyone who can prove this. So far after about 7 years now nobody has been able to back up those statements. And trust me...they've tried. Speaking with industry experts, including those outside of Wilwood, we don't know of any company who has rotors with holes cast into them. If you do please speak up.

Even the beloved Porsche rotors are noted as being cross drilled in their own literature if you were to look at it. Clearly a company who had such a superior product being cast as would openly tout that.

Net: great internet rumor.

 

[laserspeeddemon]

When I was stationed in Patch Barracks; Stuttgart, Germany. I toured the both the Mercedes Benz and Porsche factories. We followed models get made from the stamping and welding of the parts of the frame to the final product. No where did I see a rotor getting drilled. Of course, this does not say much considering the brake rotors are probably out sourced.

I don't know what you consider verifiable sources but Charles Beresford, Owner/President of Cryogenics International write:

Some drilled holes in rotors are not really drilled at all. They are cast holes. This is done to help minimize the effects a hole has in creating a stress riser in the surface of the brake rotor. A drilled hole goes directly through and interrupts the grain structure of the metal. Where a cast hole has the grain structure formed around it in an uninterrupted flow. All holes in a brake rotor will eventually show signs of stress cracking. A drilled hole will crack much sooner than a cast one. Admittedly, a “drilled” rotor will cool better than a smooth rotor, and has slightly better “bite”. However, the person who blindly goes ahead and drills his stock rotors is asking for trouble, especially in high heat or severe brake conditions. It’s not unusual for these rotors to eventually crack completely across the surface, causing a dangerous situation. Therefore, it is not recommended to drill unless it is for an under-stressed condition or, for a street car just for looks. The best solution for people who want maximum life and safety out of their rotors, is to have standard or slotted rotors deep cryogenically treated. This process performed by Cryogenics International will completely remove all thermal and mechanical stresses within the rotor. With no inherent flaws and a more uniform metal structure, the rotor will now dissipate heat quickly and evenly, wear longer, be free of vibrations. This CI treated rotor is the best performing, most durable, safe and cost effective rotor available.
Cryogenics International treated rotors are the best choice for serious applications like law enforcement, rescue, sanitation, off-road and racing. CI takes the standard rotors, drums and metallic pads you currently use (any brand) and increases their life and makes them, perform better and safer.

In an interview Dave Clark, Beresford states that Cryogenics International's senior scientist is Dr. H.E. Trucks. Here is a quick bio at the end of Clark's interview regarding Dr Trucks.

Dr. H.E. Trucks, PE is a former senior research engineer and design specialist at the General Dynamics Corp., Pomona Division.

Educated in Germany, Dr. Trucks received his Ph.D. in Physics and Mathematics at the age of 17, and his Ph.D. in Mechanical Engineering at the age of 17 ½. At the age of 18 at the request of the United States Government he moved to Cleveland, Ohio were his mother and stepfather lived. He held top engineering and consulting posts in industry and the Government.

Dr. Trucks was a chief consulting engineer for the metal cutting industry in addition to being instrumental in the design of the first transfer machine for the automotive industry, NC torch cutting equipment, robotic welding machines for the chip building industry, and NC sparmilling machines for aircraft applications.

Dr. Trucks received the Distinguished Engineering Productivity Achievement Award, recognizing him as a national technology leader, engineer, educator, machine tool innovator and executive for his sustained contributions. Dr. Trucks has also been recognized for excellence with numerous awards, honors, and commendations.

A driving force and catalyst in the implementation of advanced technology, robotics, CAD/CAM/CIM, factory-of-the-future concepts, research, automation, and productivity, Dr. Trucks brings a wealth of practical experience as well as theoretical knowledge to society.

Before Trucks turned 18 he had a doctorates in Physics, Mathematics and Mechanical Engineering. I'd say he is qualified to make statements regarding the construction of automobile parts. Also the Dave Clark in the interview is the very same Dave Clark that was apprehended in Libya during his coverage of the
events that were going on in Libya.

Then again it's just the internet, whose to say what is accurate.

Holy poop! I remember reading that a loooong time ago. I didn't realize you are the same person that started it. wow!

 

[Todd TCE]

It's some great info and insight from others also. And after all that with some of the connections the Detroit guys have (many of them work for the Big 3) or the high tech things they know about we're still waiting to see some of the proof of existence. So far it's not happened and I'm still calling 'bunk' on it.
