Downforce Question ...
 

... just curious ... if one were to add canards and a front splitter, but no rear wing, would that in theory make the back end more skittish due to increased downforce in the nose ?

If so, then I guess it is better to add downforce at the same time for both ends ... or if not then it is alright to add one end at a time ?

My experience with Z says it doesn't have a front end lift issue but rear gets very light during high speed braking. My input would be you need to balance increased front downforce with equal or more in rear.
