They say the cross drilled helps with the cooling too. Here at the dealership we sell them to all the vette owners, just cuz they like the looks. I read a really good article that explained it in a couple of ways. The biggest point to be made was the cross drilled and slotted actually take so much brake surface are away that they recommended choosing one or the other, and both for just racing (like scca, not drag). I know in the past they were prone to some cracking, but now they seem to be under control. They come drilled from the factory on the Z51's, Z06's, grand sports, and the ZR1. Speaking of ZR1 we did just get a Maroon one delivered. That is such a sexy color. Ok back on topic. On something like our car I would think the slotted would be just fine.
If your going for looks, get them they do look good!
Budget minded, why not look at the gm ones?? I can get you the part # there sold under the delco name. Or just go back to the stockers. Or upgrade the spindles to the S10 blazer and run 11in rotors with dual piston calipers. Then upgrade those rotors, if you have to buy them anyways. I bought 2 complete knuckle assemblies through LKQ for 49 a side. Just havent put them on yet. I figured I would at least use up the brakes I have. lol
I dont think you ever did say why you wanted them to begin with.
