Mopar Performance circle track springs are an option.No...they are not stiff, the ride is excellent, i have used them.They will lower the rear, improve handling and have height adjustments. I believe they are still available and reasonably priced.
Ehh, still available is a bit of a question mark and whether or not you actually want to use them is a different story. The manufacturing location has changed a couple times and at least one run of them was not particularly good in the quality department. I’d love to still recommend those but unless something has changed with the manufacturing quality quite recently I wouldn’t get them.
