Matt unfortunatly this is what happens with most cars . Unless the roads are really good the ride is pretty harsh with good race susspension.
What kind of spring rate are you using?? I had 200lb with my A14 and now have 275Lb with the ca18 Im quite happy with this setup its ok on good roads but need a kidney belt on rough roads. Its brilliant on the race track.
I have seen some spring setups with like a short softer spring up the top I pressume this would help. The first bit of susspension travel would be a bit softer and once it has reached its limit it works on the harder springs.
Errol may have nore information Im pretty sure I saw that kind of setup with one of his SERIOUS struts.
