I believe those are some older Hyperco springs. They should have the mean rate etched on the bottom flat of the coil. High end quality springs made in America. You may try emailing them the picture for some latest info / support.

Then also a great set of RSR type threaded body Bilstein struts that still look good. The billet machined spring hardware is decent too although I would suggest installing some spring seat bearings to prevent the coil binding. The main coil could be supplemented with a tender or helper spring to take up some slack.

Generally with a softer rate the tuning can be achieved by the anti-sway bar that you have. Great set up, hope this helps!
