Good fast-road set coilies will be more than enough for light track work. A full-on track suspension is far too hard for public work, not to mention the expense of having track dampers serviced so often. I often think that some folk go far too aggressive with their suspension on track cars. 3-way dampers etc is complete overkill for all but the most dedicated track day car, you need to be racing on a regular basis to get the setup right and get to know what settings you need to tweak from track to track and how far to take it. 99% of the time the extra cost of super dampers like that is better spent on driver tuition and a decent geometry setup. That said, those Tein coilies look rather excellent, as long as you can find a good road setup then you're on for a winner.
