Cal Tracs rear suspension or multi-link suspension kit?

I put Caltracs on my 68 Dart and their split mono leaves. I bought their 225 lb spring rate leave springs because I wanted to be sure to stop any wheel hop. My Dart is a manual transmission big block. It is not a fast car by any means, but I do plan on taking it to the drag strip. I have 90/10s on the front, cheap adjustable shocks on rear. I told the guy at caltracs that ride stiffness did not matter to me just that I didn't want wheel hop. Well I got the no wheel hop, but it does ride like a brick. Very stiff riding car. Would not be a great setup for carving corners for sure. I am fine with the ride, but a lot of people would hate it. I just got the standard height rear leaf springs from Calvert. I have no loyalty to Calvert Racing so I thought this reply could help. For traction they work great, just be prepared for rougher ride.
