They work well...for about a year, then they lose their arch.
The Superstock Springs were originally designed for the early 62-65 B-bodies. '63 has the same spring segments and lengths as an A-body.
We've had more consistency and longer life out of Cal-tracs and split mono's.
As for ride, we had the 456/457 3400 lbs. springs. The shock you use makes a big difference in ride quality. My Calvert 9 ways ride like crap on #9 setting but calm down and ride comfortable on the #4 setting but the launch goes away.
