Is this normal?

So i finally got my drilled/slotted rotors in for my apri rear disc swap and uh.. well.. somethings weird.



Although theyre opposite directions which is great, they're not exactly the same. Before i send them back is it possible they look different from side to side?

Sumthin ain't right. Are the centerbores the same? One of the left looks smaller..The cutouts on one side don't matter much but if any dimensions are at all different, it's time to return that lot and have 'em try again!

The one on the right does seem a tad larger in diameter. Also, why is there material missing from the hat on that one? And is it just me, or are there some weird machining marks on the outer edge at around the 10 and 3 positions? Check the widths of the rotors, too. Something about those doesn't seem quite right. Where'd you get them from?

Ebbbaay! I'm gonna call em on Monday.. weird thing was the boxes had the same part numbers on them.

Sometimes the wrong part gets put in the box. I've seen it happen all too often, even at a dealership. These things happen, I suppose. I just hope they work with you to square things up. Keep an eye on the rotors once you get them installed, too. I've seen quite a few of the non 'name brand' drilled rotors crack around the holes after a while. I'm sure even Brembos will after a fashion, but some tend to do it sooner than others.
