They are GM/Brembo replacements for a ZR1, think they are like 2006 and up?

Prices vary a little depending on seller, think like $1300 - 1500 each or so ? (I didn't order them so don't know for sure) just looked around a little online out of curiosity.

I have front and rear rotors and all 4 calipers laying around until I send them to Oz.
