I got it bud, thanks.
Ran teh car this weekend after a complete rebuild.
Needs a bit of tweekingto settle it in but again as mentioned in my post above, soft tyre shores and i was all over the place and as soon as i went harder car got more planted.

Next national is at the ned of march so have some time to get it in the park.
Must say i use darren Johnsons spool setup as a base and its always close to where i need to be.
