My springs have been on both cars for years. They function and ride better than any other spring I've tried including various other SS springs and Calvert's Caltracs with split mono-leafs. I was lead to this simple and effective solution by Dr Diff, and it works brilliantly.
I recently beat a Hellcat with my set-up during the Drags at Willow Springs Track Day, so it launches pretty well, rides better than ever and corners great. Although, I am using slapper bars that suppossedly don't work on Mopars either.
