I've got the LS1 calipers, have already turned my hubs, I've got some adapter brackets per Pozzi Racing. Now which rotors do I use. Do I use C4 Vette or C5 vette. I know they are supposed to be 13", But which ones do I use? I would like slotted and drilled. Which ones would be decent off of Ebay? I know that I have to use the LS1 pads and not the vette, but which rotors? I know everyone says to call Kore3 for the brake lines that adapt the metric calipers to the standard thread hard brake lines, correct? I've been dragging my feet on this project. My car is down and my kids are giving me hell about it. It is kindof hot down here. Its over 100 degrees. Thanks Keith "Round Tuit Garage", the name says it all!

The rotors you use should be determined by the adapter brackets since those are what determine both the radial and axial offset of the caliper which must line up with the rotor. I'm assuming you would be looking at running the 1988-1996 C4 Corvette rotor for the HD application (13") since you mentioned the diameter.

Aren't the C5 rotors 13" also?

No, C5 rotors are 325mm [12.79"] diameter and 32mm thick [1.26"].

The C4 HD rotors are 330mm [13"] diameter and 28mm [1.1"] thick and have a deeper offset which can be useful with respect to wheel fitment. The downside is that the rotor is 4mm narrower than the rotors that the C5/LS1 calipers are designed to accommodate.

Thanks for all the information.
