This is because the adjustment changes damping settings, but spring constant stays the same. At the softest setting, they will be bouncy. At the hardest setting (harsh on the road) they might have the optimum damping, or be over damped. Buying super stiff coilovers and setting up on the softest setting for the road will only end in tears. Get the right spring rates, then match the dampers to suit.

As to the original question, changing from your existing springs to coilover sleeves will do little apart from maybe open up a wider range of off the shelf springs. You can have a good compromise between road and track, without going crazy either way. Talk to a suspension shop to see what your options are. Konis tend to be a reasonably good off the shelf damper, so if matched to decent springs and good geometry, you should have a well balanced car which should perform well ont he track. If you're chasing trophies, then maybe you need to look at something like Penske or MCA suspension setup, but at around $10k for the setup, it's not for the faint hearted. Totally overkill for a weekend track car.
