Both changes increase roll stiffness (not bad by itself) but most importantly keep the roll centres a bit higher (they are bellow ground stock, that is a crutch).

3. now that you've increase roll stiffness you have two options, 1 if the car is too stiff and the wheels get off ground at every tiny bump them the springs are too stiff and you need softer ones. 2 the car is too responsive during cornering, increase camber link inner shims by 1mm front and rear and use thinner roll bars.
4. I think your front bushing configuration is the culprit together with the flex. See the Ford GT arm sweep configuration.
