will ls1 rear rotors fit on my lt1 rearend are they the same size? thanks for any info

 

I know they're bigger in diameter, I think they're a little wider too. They won't bolt right up, do a search on the 4th Gen forum, it's been discussed over there a bunch.

Check out this article--it's for putting LS1 rear discs on a 3rd gen rear, but they're basically the same:
