Since thats a pic of my car, il write my thoughts:

I havn't raced mine in mod at a big race yet since the new parts (only practice), but in 19 turn it felt good at the champs. I ran an earlier version of the car at Vegas in mod, the car felt decent but had a bunch of issues power wise holding it back. After running mod in practice back home it feels much better then the older version, i look foward to racing it in mod now.

CG wise its not really a problem since the car is so narrow, the slight amount of weight it has higher would if anything make it feel more like a standard car (more roll)....but it does still transition better then any other 12th i've raced.

As far as weight foward, i had my electonics mounted back to play around with it, and it is a great tuning aid to be able to change the weight balence pretty signifgantly. I am still trying to decide what i prefer, but i think back is easier to drive faster, foward may be better for certain condidtions.
