Discovering the real source of the bounce is the issue for me. I am beginning to question whether it is actually due to shocker action or is the bounce coming from the tyres as you go over bumps due to the springing being a bit stiff due to new tighter bushes?. Setting spax on full hardness does not seem right and does not seem to correlate with others on here.
I drove my friends gdi plus4 last week that has had SSL front and rear 500 miles ago and it seemed very good, with a setting of 6 up from soft. I am running on two and it’s not bad but still not as good as expected for such a large outlay.
Depending on how many miles you have done since the changeover, it may be worth going back to the workshop and do a test run with one of their technicians to diagnose the issue.
Like you, I am wishing I had kept the old bits!
