Hotchkis leaf springs?

I just installed them on my 70 Duster using DoctorDiff's 1/2 offset hangers which have 2 holes. Comparing them to the Hotchkis hangers which supposedly lower the car 1", I used the upper hole. I also put on the RCD Bilsteins. It went together nicely and the car rides great, but
the tires were definitely hitting the 1/4 lips which helped, but while more stable in the the corners, while driving aggressively it seems to bottom out on the bigger bumps and ruts. I'm thinking it may be too low.
