No confusion on my behalf Stu but for newcomers there is and don't forget you were in that situation not so many months ago, seeking the advice of others to get your racing equipment and knowledge to the level it is today.
As for the Zen I'm sure you will be more than happy with it and it's relative simplicity compared to the SSGT but I did find my RSGT12 Race needed some work to get the front end as specified, this required some judicious sanding of the strut bases to achieve and match the 2 degree negative camber and ride height on each side!
I must admit the strut mouldings are not as good as the original Associated ones from the RC12E and its variants of many years back but the rest of the bits are nicely made!
Happy racing
