Ever seen a Brake Rotor like this?

[CamryOnBronze]

So I went to install the Wilwood kit I got used form a zlivia member last night when installing my Ichiba hubs and I ran into something I have never seen before. The kit I bought was the 12.9" rotor kit, but the seller didnt want to sell the actual wilwood rotors at the time. He told me he had a hookup on blanks and would give me some brand new blank rotors to use with the calipers/kit.

When I tried to slip the rotors onto the hub, there seemed to be a lot of resistance. After further inspection, I realized that it looked like the rotors were drilled for a different sized stud and someone had smashed little metal spacers into the holes in an attempt to make them fit 5x114.3 studs. I also noticed that one of these plugs was missing on one of the rotors:

Needless to say, this is pretty jenky. They might slide on with a little force, but I am not going to risk messing up my studs. I feel like I am basically screwed at this point... Wilwood rotors are about $400, so I pretty much feel like that this point I would be better off selling this whole kit and buying a brand new kit or 300zx brakes.

I guess I just wondered if you guys have ever seen such a thing and if you think there is a solution. I dont really feel comfortable running these rotors on my car unless someone can show me that this is a legit thing, but I do not think it is at this point. Oh well, live and learn- dont try to cheap out on shady used stuff.

go throw them at the guy's (seller) face
those look janky and ghetto, i have never seen that

That is what I thought, I have never seen such a thing... for sure not fit to be put on my car.

Oversized stud holes don't matter if the rotor is hubcentric. They just locate it to the hub, the center bore is what actually centers and aligns the rotor. Knock those spacers out and check it, if it's truly hubcentric you're fine.

Anytime I redrill 4lug rotors to 5lug I always go up to a 14mm hole to factor in measurement and drill offsets. Sometimes even when you measure dead on you can be off a hair, making the holes larger ensures it will slip on the hub without damaging the studs.

Ill have to look and see if they are hubcentric or not, thanks for the heads up.

No problem. If it isn't you might can get away with using a hubcentric ring, although you would need to know the bore size on the rotor. I'm assuming the blanks aren't Wilwood so they may be a generic size, like 73.6mm.

[CamryOnBronze]

Yep, I was told the blanks are brembos, but I dont think they are... could be I guess though.

So if it was hubcentric, the rotor would be centered obviously... but wouldnt I still have to worry about it moving from side to side on the studs? Or do you think that the lugs holding everything together would be enough to keep the rotor from moving anywhere?

Lugs will hold things together.

weird. you're fine without that rotor plug just so you know.

if the rotors were redrilled to fit 5x114.3, do you really think the vehicle they were originally intended for would have the same hub size as his?

common sense tells me no, but i guess i could be wrong.

bring it up to whoever sold you the rotors and try to get some kind of reasonable explanation for the ghetto-fab rotor work.

Nobody said they are redrilled. It looks like the rotor was made to be universal between more than one vehicle, and they used the reducers for the holes instead of making specific rotors for your car. I wouldn't have even taken notice to it as a possible problem myself, if it fits its fine. Make sure you are sliding it on straight, it might be binding up a bit if its tight.

[CamryOnBronze]

The reducers are extremely jenky... they look like just sections of pipe that were hacked up to go in there. They were for sure not made as reducers or machined that way, they are all chopped up and have a rough finish. On top of that, they dont even fit onto the studs very well. They might go on if I used some force, but I dont want to mess up the brand new studs on my ichibas.

I think I am going to get what I can back from these (with actually making the buyer aware of the issue) and go with a brake setup in better condition (new). I have messaged the seller but dont expect a respons since his timeliness with shipping and communication were poor to begin with. That's what I get for trying to cut corners.

Thanks for the input guys.
