Neil you CAN get it comfortable with fine tuning to the Compression and Rebound.
Camber and toe kits are also only required if your drop is excessive. If you went for a moderate drop (say 20mm) then there is sufficient adjustment on the the rear camber and toe to compensate for this and the front camber will still be within factory recommended tollerences, so expensive aftermarket camber and toe kits are not always required.
Regarding the set up for your car, I can assure you that a compromise can be reached to give you the ride comfort that you are looking for when on track and road.
However adjustment is very easy on the KW3 and only takes minutes to adjust the compression and rebound.

I run adjustable coilovers on my sc mx5, after finding my ideal ride height (just high enough to get over the usual speed bumps) got the alignment sorted then went about setting the compression & rebound settings. I now have 3 settings I use, Wet roads/cruising Dry/fast road & a balls out track setting simples
