Camaro disc brakes

[big gear head]

I'm trying to take some of the drag out of my '69 Camaro. The front disc brakes drag a lot. If I try to spin the front tires they only turn about 1/4-1/2 round and stop. Is this normal for the factory disc brakes? I rebuilt the calipers several years ago. I'm probably going to use Wilwood or other after market brakes on it due to the drag of the originals. Any recommendations for good after market brakes that will work on the street with low drag?
