They should work with the springs, but it probably depends if there's any dependency of the position of the damper as it will have a new nominal position. I don't know enough about DHP to tell if they vary the damping overall, or also by the position of the damper.
For what it's worth, the service manager at Turner has a 35i with DHP, that's the one in the pics on their website.
