My understanding is they are not a Drag race specific
spring.
The SS and Calverts have a totally stiff rigid front segment, basically
that work like a traction bar to transfer the torque to the housing and thus
the tires.
I can give a more detailed analysis when I am not 1/2 asleep.
Correct, the Hotchkis springs are a handling specific spring, not a drag spring. Their literature says they have a stiffer front segment than factory springs, but I haven’t run a set to really evaluate them.
Their “geometry correcting” front hangers lower the car about 1”, and it should be noted that changes the angle between the front and rear eyes of the spring which can change the launch characteristics.
