I got these rotors in a GD and im not sure if they are the right ones. Both are different, The boxes say 1 piece R Nissan, it is 20mm thick and the other one says 1 piece F Infiniti and it is 8mm think. The 20mm thick rotor looks like this one... http://store.yahoo.com/southwestauto...smaxbrem1.html The 8mm rotor looks the same but it is not milled in the middle, its solid and only 8mm thick. Is this right? I came across this writeup on front breaks... http://www.motorvate.ca/mvp.php/302 and the rotors look like the 20mm ones which say they are R (rear?) on the box. Can someone straighten this out for me?

 

sounds like you got 1 rear and 1 front....the solid rotor should be the rear....and the vented one (milled in the center) is a front...sounds like someone mixed the rotors in the boxs

 

I have all four rotors and wasnt sure why the thicker ones were rear. They were all in the wrong boxes then. Thanks a lot for clearing that up.
