Cal tracs on the street?

I'm with JBC on the ride. I had 340 HD replacement springs on my car and it rode good and my build is about the same as yours Erik (500 hp 408, 904, 3:55's) and it didn't hook up at all, even with Nitto drag radials. So I put Cal-tracs and springs on it. They didn't rattle but they sure ride like a freaking log wagon and the aluminum bushings squeak even though I lubed everything up real good with moly paste when I assembled it. I recently pulled the springs out and swapped out the aluminum bushings for polyurethane bushings and that took care of the squeak and make it ride a little better. I also installed Mickey Drag radials and now it hooks good. The Mickey's made a tremendous difference
