I believe a few of the posters here miss how a
suspension is suppossed to work - the chassis needs to be as completely solid and stiff as possible and the only real job of the springs and shocks are to keep the wheels planted to the ground.
If you have too much flex in your chassis, then it makes it much harder for the springs and shocks to do their job and in most cases when you feel every bump it's because the chassis is tossing you around, not necessarily the bump itself.
Here's my experience from a convertible owners point of view:
I've learned the hard way about these suspensions, I started out with Monroe sensa-tracs believing their BS articles. They made the the ride worse because they were way too loose - I'd find myself in a corner with the rear tires breaking loose way too often and not feel it coming on. Then I bought the KYB's - no better at all, I think they may have been too stiff for a convertible. Finally I talked Jon Dega from Springfield Motorsport and he explained to me that what I really needed was to stiffen up the chassis - he installed subframe connectors w/ extreme matrix and strut and g-braces and it was a HUGE difference and I still had the stock springs and KYB struts. A few months later he installed the CC plates and again there was a huge difference in cornering ability.
Finally a couple years after that I installed the Bilsteins and
Eibach Pro's and the ride was much firmer, but to me it was more comfortable because I felt more comfortable going into turns and launching was extremely improved. So I'd highly recommend tightening up your chassis before playing with your shocks and springs.
Just thought I'd share my experience.
