I did some research to see what I’m getting here. These are made by winhere, obviously MADE IN CHINA! But, their webpage in CHINA states that they make lots of discs for oems such as Audi, Honda, ford and several others. The ultra HC rotors are listed on their website so, all in all, they’re legit. That doesn’t mean that they won’t suck. It just means that they’re not some rotor cast from someone’s garage and sold at Walmart. Who know, maybe I found a hidden gem. Shall see. At $100 for all 4 corners, plus living in the rust belt, if they don’t explode on a trip up north and last a few years, I’ll be happy.
Ultra HC rotors
- Thread starter D1dad
- Start date
These were a more of a battleship grey color owing to the zinc in the coating.
So I received the front rotors for my 18 rogue yesterday, the rears show up today. Impressive finish and weight, definitely geomet finish. But, there’s 2 holes between where the studs for the lugs go. Almost looks like a place for a mounting screw would go to hold the rotor to the hub. I haven’t pulled an old rotor to match it up to make sure it’s a correct fit. I don’t believe you’d see these holes when the wheels mounted, but I know my existing rotors don’t have these. Color me confused.
No.
High Carbon in itself doesn't really mean much....it was branding that was sort of adopted by everyone....
Rotor material fits into 2 basic catagories.....normal and soft. Your conventional rotor you'd find on an asian or domestic vehicle is going to be G3000 (or something similar). Pretty hard iron, relatively speaking, designed to be used with an adherent type pad. This is why we see very little rotor wear on domestic and asian applications.
The "High Carbon" (or "dampened iron") rotors are a softer iron, mostly used on euro applications, or domestic/asian vehicles using Euro brake systems (Ate, etc). These are designed to be used with an abrasive pad....both the rotor and the pad are designed to wear (and make a lot of dust).
A High Carbon rotor will be of limited benefit when using an adherent pad. A conventional (G3000) rotor will likely be noisy when used along with an abrasive pad.
It's more about the material characteristics than the carbon content, but some manufacturers, in an effort to jump on the bandwagon, just added a bit more carbon to the mix so they're able to call it a high carbon rotor, but it doesn't really have the same characteristics of an OEM euro rotor, which is really the goal.....other manufacturers hit the mark nicely.

Well, I kind of indicated that. Pagid advertises actually their rotors for last 10-15yrs as HC rotors. Brembo categorizes most Euro line-up as HC (I will come to those that don't later).
Actually, Euro manufacturers use both types of pads on normal and soft rotors (HC). VW switched to American-bound models (Atlas) to rotors that are also used on Asian vehicles. However, they retained very aggressive pads (ZF). Rotors are junk. Pads are excellent. ATE rotors solve vibration problems that OE rotors are prone to (Brembo made). Brembo classifies those as normal (non-HC designation).
BMW on F30 used on some models (335/340) three types of pads and two rotor sizes. Rotors were 340mm or 370mm (M-Sport package). But, you could get three types of pads (Both rotors use the same pad): Base (no dust whatsoever, adherent pad), M sport (P337, also no dust whatsoever), and S2NHA (base pad in Europe, super aggressive, high dust). That was an attempt to lure in buyers of Audi, MB, Lexus, trying to be everything for everyone. There was no difference in rotors that go on different pads (harder for adherent pads, or softer for abrasive pads).
Euros do come with HC content. However, as I mentioned, that was never advertised. HC thing was an attempt by some aftermarket manufacturers to get some better marketing results. ATE, Textar doesn't advertise it. Pagid does. Brembo does indicate which are HC, which are not (Euros are, Asian/domestic, and some VWs are not). EBC does not advertise too.

That does not meet much. It means they might have certain qualities that they adhere to, but those rotors are far from what goes on at Audi, etc.
Car manufacturers set requirements for rotors when they are buying from ATE, Brembo, or TMD (like Audi does). Brembo will deliver for certain Audi models exceptional, and VERY expensive rotors. For some models (VW Atlas) it will deliver, what can only be characterized as junk. Those Chinese guys are making rotors first and foremost for brake manufacturers. I had ATE front rotors, made in China (could be the same guys that made them). They did 40,000 miles, of those 40,000mls, 3-4000 was on track utilizing racing pads. I can guarantee you that 90% of rotors won't make 5,000mls if you used them 500-1000mls on track with racing pads. They will start to vibrate etc. And they were, IIRC, $57 per piece for front. The brand name does play a big role here. They set requirements if someone makes rotors for them, although ATE probably has its own plant in China.
The price point is generally not the best indicator, but $100 for all 4 corners is bit too cheap.
They are holes to thread a bolt into for forcing the rotor off the hub when it's time to replace them.
Handier to twist in a few 8mm bolts than to smash away on a rusty rotor.in a few years (assuming the threads don't strip out of the hole). Other rotors with this feature make it really nice in the rust belt when you don't have an air hammer to rattle things loose.
I agree on the cheap part. Had I went to advance (who sells them) I’d have been looking at around $300. That’s Brembo and almost ebc territory. I’ll not welding them to the hubs. If they don’t work, they’ll get ripped off. I change pads and rotors more often than some on here change oil. Literally!
I installed these last week, after a caliper issue of my own creation. I used green stuff pads which are advertised as easier on rotors…. shall see about that. We ran the rogue about 900 miles since with 600 miles being a road trip to hocking hills. I was meticulous on cleaning the rear hubs, I replaced the fronts so no cleanup needed. I won’t make these things out to be Zimmerman until they get to Zimmerman durability. But, no complaints. The ebc pads scrubbed them to a mirror like finish and an 80-10mph after they were seated revealed no vibration whatsoever. They feel solid, dead silent and the finish is as good as EBC. For certain applications like my 18 rogue, they’re dirt cheap. For my 21 and 24 Altima, they’re ebc money. I ordered another set for later on, @ $20 a rotor, why not. I’ll update after a northern Ohio winter on how they look. For now, no regerts!
