Easy
Number 1
Before you do anything talk to experienced people (not gash forum mates) with a pedigree, technical knowledge and track record of running and setting up similar cars. Take independent advice on what you want to achieve. A track orientated car will be a completely different animal to a mostly road car. This needs to be done before you buy anything. 2 way adjustable dampers on hard springs may not be what you really need. Talk it through. There is no one single right answer. Buy to achieve your aim. Be realistic about your aim and the compromises they will bring. Research and justify spending the money. Track instruction can be initially cheaper and more effective for example.
Number 2
When you have the right kit for the job, or you just like spending money..... Get it corner weighted. Essential. Never scrimp on this for road or track work. If you are aiming for track work, get it balanced on the scales with driver and mid-fuel track weights (if that is your priority) for the balance you prefer. Near balanced front platform weights will skew the rears a bit but gives you consistent front braking loads. That can be good for racing if that advantage under brakes is significant etc. Again talk to people that know. What may be right for me or you won’t suit others.
Number 3
There are no magic damper settings. Each car and driver is different. Each day is different. So set fully soft, fully hard and feel the extreme range. Then play tunes to get what you feel is about right. It’s about experimenting and building a knowledge database. Settings for Oulton? Completely different for Dry or Wet or for Silverstone. Only adjust one area at a time. Playing tunes with damping, tyres and weights with one hit just confuses the outcome and response. Remember a cold Oulton will drive completely differently to a hot one, a bit of understeer on one bend may be neutral on another. Where is the trade off and max advantage to be gained if you try and chase neutral everywhere? Most people will end up with stock settings for various situations. Road, track etc.
You will never get a definitive checklist of this stuff and that is why race teams have experienced people reacting to the varying conditions and situations with a hard won database of what works.
