Improving my s2 suspension

It's a Spanish series 2 with a reverse pull front disc. The brake works well but there is a bit too much dive under sharp braking.
At the moment I have Scootopia progressive springs and cheap (non Escort) dampers. Back shock is a standard one I bought years ago. I deliberately didn't use MB springs as I have found them a bit harsh in the past. Perhaps I should have.
I am of the belief that merely putting good dampers on will not sort the suspension properly as the rear shock is part of the problem too. But, I plan to get new dampers first and , when I can afford it, a new rear shock.
I have never heard a bad word about the bgm adjustable dampers ( other than the price that is). Would these alleviate most of my problem?
