You need to look for a setup sheet thats close to what you are driving on, grass, astro, carpet. you won't find many for the ZX-5
get some blank sheets and note your starting positions, make small changes, one step at a time, make notes, so if you notice improvements you know why, if things get worse you can back track.
Here is a setup thats easy to understand

i may/may not apply, but you can see which holes Pavidis used. you can navigate to this sheet from the oOple kyosho setup links, a lot do not work, but still one or two in there.
afterthought: What works for other drivers may not work for you, driving styles vary, specialy the top guys
