You'll have you teef knocked out without progressive springs....... just a thought. How much is the car expected to max out at? Have you got a bail out fund?

how would progressive rate springs knock your teeth out?
they're designed to NOT do that...

and comparing his suspension to other cars going... it shouldn't be that bad... ;)

The current setup on the shocks is quite soft actually, yet the car feels grounded significantly more than it was before.
