Race Craft makes a suspension aid. its called, assain Bars. I have read and heard they do work and are effective on Mopars with Super stock springs. they need some adjusting and such but what doesn't. they have a lot of holes for different adjustments. they guys I see run them are quick in 60 foots.
Just my two cents
I was looking at the Assassin Bars.
I am using front spring hangers to lower my car. If I install Calvert's the bottom of the spring hanger will have to be trimmed to make clearance for the front bracket on Calvert bar.
With the Assassin's I don't think there will be any interference.
