Beat A Dead Horse Demon Suspension Recommendations

I think you are selling them short if you think they can't. My car rides and drives just like my 2015 Challenger R/T did.

No, I have not decided yet. If you say your car rides and drives great, I doubt the only thing you've installed suspension-wise was the torsion bars but that's all I've been hearing so far on this thread. If you lay out exactly what you've installed then I can compare and contrast.
