I guess where I was coming from Paul is that from a geo set up perspective, as well as knowing where you're coming from (what's your set up now), it's knowing where you are going to and the difference between the two. From previous set ups I've had (by Chriss too), you should be able to get the target data (manufacturer, race etc) to load up and the system will inform the rest.
It's the Porsche factory CS target data I'm after to compare how far (if anything) mine have deviated from (ignoring personal preferences etc). Feeling I'm proabably reaching the stars with this one unless there's some (industry shared) database from all manufacturers.
As you say, Chris can fill in any gaps. However, I do know SuperPro bushes and new mounts really improved things on my 911. Wear and tear comes to all...
