I need a little help. I have no problem finding the part numbers for all the Z06 parts, but i am wondering about the C6 z51 parts. I am going to weigh my options, either one will do the trick. The Z06 setup would look better I am sure, bigger rotor behind Jasons wheels = sex! But, the calipers are going to cost me 210 a piece, rotors, just under 100. I bet the z51 calipers are around 100, so after factoring in the cost of pads, I bet I would save nearly 500 dollars with the kit. If anybody knows the part number for the c6 z51 brake calipers, please do share. I am having difficulties finding them on the gmpartsdirect website.
