Do coil spring assistors need stiffer dampers?

I have a Granada Cosworth rear end, one of the dampers sprung a leak so I bought a new pair.
The new ones weren't pressurised like the old ones (the old ones rapidly extended by themselves when removed) and the suspension was a lot softer and often bottomed out.
Now knowing that I needed different dampers, I bought a pressurised pair but Sods Law prevailed and they weren't as pressurised as the originals and I still had bottoming out when loaded.
Rather than spend out on yet another pair of dampers that may not work (unfortunately I didn't think to take any part numbers from the original leaky dampers) I thought I'd try a pair of those rubber split doughnut things that you thread in between the spring coils - they were cheap (~£10), seemed to make the suspension stiffer and cured the bottoming out.
BUT, the back end now feels a bit bouncy and underdamped - does it sound likely that the rubber bits to could increase the effective strength of the springs to the point where they overpower the dampers?
