Hello,

I need some advice. I just received some new one-piece brake rotors (front), and I have noticed that they are slightly different. Both rotors have the same part number, but there is a difference in the "hat" area. As can be seen in the picture, one rotor is built with a 90 degree angle (square-ish) where the "hat" area joins the rotor. The other is built with a rounded or bevelded angle for this connection. Also it can be seen that the square one has a bigger lip (approx 1/2 inch), as compared to the rounded one. I'm guessing that the PAD contact area is what is important, so this might not be a problem, since the contact area will be in the outer edge of the rotors. Is this the case ?

Also, I can see that the rotor sandwitch plates (for lack of better words) are different. Thicker in front plate on once / thicker on the back plate for the other. This can bee seen in the pics, though overall thickness seems the same. Both rotors have the same diameter / hub size etc.

Will any of this be a functional problem, or is it just the looks? I'm debating whether I need to return, but I'm torn since this would be my second problem with this order, and I really need to get my bakes fixed asap.

Thank you.

 

What brand are they and where did you buy them?

 

Centric part # 121.42070

I don't want to name the vendor at this point. If I need to go back to them, I will try and see how it goes.

 

i wouldn't put them on my car unless both were identical. if i were in your shoe's, i'd be calling whoever sold these to you

 

I agree.

I can't think of anything more important than your brake system, don't chance it.

 

Yeah, thanks. Made the call. Replacement is on the way.

 

Poor quality control but I see no functional problem.

 

Good choice. I wouldn't install them like that.

 

Suprised to see that from centric....

 

OC Autosport? I have the same set up on my car with no problem at all.

 

R1 Concepts. Definitely a quality control issue. I had to do two returns on this order. Wasted a lot of my time and also some money.

I have them installed now, so I can only hope they hold up.
