See, now that is a problem, rust in the holes is a bitch. Contact Sam, see what he can suggest? Let us know and thanks for posting the review, very helpfull to the rest of us.

 

I dont care, I am offended, because of his and other similiar comments.

 

I thought that these rotors were supposed to be zinc plated. If it were, I highly doubt I would have rust developing in the holes themselves. Other than that, these rotors are holding up very well and the stopping power is good. As for now, I would say to stay away from this brand of rotors until I get some answers from Sam and see what he has to say. I will post his response to me when he msgs me back.

 

Like I said Filanj, I don't know much about rotors and I did a search on this forum and the group buy came up. People gave good reviews and I went ahead and purchased them. Again, I was failing my inspection due to my rotors so I needed replacements asap.

I did not know that these were ebay rotors, but now that you have provided links to the auction...I do. Thank you.

I will look into the suggested rotors you have provided. Thank you for posting links to them.


Edit:
Just checked out those links. Those are for the coupe and coupes with brembo. I have neither. They don't have rotors for sedans available either. Thanks anyway.

 

Your a moron, I do value My car, I cant afford a Lambo. If u insult people who own them then u should get a pricier car and u wouldnt have to read comments like ours. By the way since u want to help RXM now after u laughed at him why dont u give us a personal review on the Rotors u have and post some pics. We really want to see what mods u personally suggest. If u dont want to post pics or cant make specific reviews than u should get out of this Thread because it was started to comment on R1 Rotors, which u dont have and dont want anyway.

 

filanj: you aren't adding any value to this thread, why don't you find another thread to move onto and correct grammar?

To the others: I'm curious to see what Sam says too, in the original thread, a few people have said these rotors have been holding up well ... one person quoted 6 months of use without any issues (https://g35driver.com/forums/showthr...+months+rotors).

Some rust is inevitable, but it usually comes off under light braking. I wonder if the rust in the slots is an unfortunate by product of Sam specifically making us slotted rotors? (not that it makes the rust OK). BTW- some pics of this rust would be helpful

 

I think we can all agree that the G35 is a great car and leave it at that. Whether or not the car is expensive, it is all relative to your income.

I think we should bring this thread back to focus about the rotors and stop attacking eachother. I think we have all said what we needed to.

I posted here so that others can read my experience with the rotors and judge for themselves if they would like to go this route and for others to chime in about the rotors. Lets stick to the topic.

 

I will post pics asap. It has been raining all day and it still is raining where I am. We got that nor'easter that came from southwest and it has been flooding our area. I don't want to go outside with the camera and get it wet I will post pictures tomorrow when I get to work.

 

I wouldn't be so quick to correct people's grammer.

It should be "hence" not "hense". But this isn't school and mispellings happen all the time as we type. As long as the point gets across, things are just fine the way they are

 

Cool. Before we go and jump the gun, a quick question for you, have you actually confirmed that the rotor rust won't come off after you brake for the first time?

 

After I saw the rust on the rotors, I jumped back in my car and drove to the mall (20 minute drive of highway and stop and go traffic) and the rust was still there. You will see what I'm referring to when I snap some photos tomorrow. Sorry I didn't get it today, but like I said...damn weather

Edit: It could be that due to the weather, the rust formed again after I stopped driving and got out of the car to look. I really hope that is the case, b/c if it is, I won't have to buy new rotors

 

That a Good Point, The humidity can cause the Rust. I will check back in a few days. I hope u can give us an update when the weather clears up. Im in New York and we also got hit, matter of fact it's still raining.


I cant beleive there is over 30 comments of us going back and forth on this subject in one night!

 

Haha...most of the posts were just to insult me so I don't think those count towards anything. I don't think that the rotors I received has the zinc coating and I'll tell you why. On the front rotor, around the hub...there is about a 1/2 inch of rust all around the rotor (towards the center of the hub - where the pads don't contact). Since the pads don't rub up on that area, the zinc coating (if there were one) should not have came off and the rust should not be there. This is why I believe the zinc coating was not done. If I had known that these rotors would not come zinc coated...obviously I would not have purchased them.

 

everyone must keep in mind that rotors are made of iron, which will rust. they are made of iron because of its heat soaking abilities, and its ability to remain ductile even under such a high heat stress. for brake rotors, iron is a much better material than, say, stainless steel.

now, while some rusting is acceptable (especially after getting wet and left to dry), the rust that you are talking about RXM, is not. the surface rust should definitely have come off after driving it around (especially in stop/go traffic for 20 minutes). as for the "zinc coating:" it's usually a marketing ploy...but, most rotor manufacturers do offer this coating to protect from rust in certain areas. know however, that if this coating is on the surface where there is contact with the pad, it will just rub off. this coating is mainly beneficial in the pillar vane (interior of both dics) and the hub area where there will be no contact with the pad. these parts shouldn't rust for a very long time because of this coating.

the rust inside the drilled holes are a different story. whether those were "coated" or not, i am not sure. but be wary of cracking (even hairlines count).

just as an example...i have brembo slotted rotors (from tirerack). when i was my car and hose down the wheels/brakes, there will be a slight discoloration on the surface of the rotor (where the pad is in contact with it)...it's a light rust layer (it oxidizes that fast). but when i'm done washing it and pull it back into my garage, it's gone.

 

Hey N1ck, thanks for chiming in man. The rotors do have a coating on the hub and pillar vains. It looks sharp with the black coating there. The problem I am seeing is that on the rotor itself, there is a portion that does not get touched by the pads, yet they rusted anyway.

Do you have any recommendations for rotors?
