ls1 calipers with c5 rotors 1st gen drum spindle?

[junkman]

I have the complete front brakes from a 99 t\a I parted out. I picked up the adapter brackets from the guy listed on the pozziracing site to use the 98-02 calipers/rotors with the 1st gen drum spindle/hub. I was going to buy a new set of rotors, and was wondering what would be involved to use the c5 13" rotors. Would I need the caliper bracket from c5 calipers, or a different type of adapter that bolts to the spindle. Thanks
