driving capabilities with a wider rear?

[Apolan]

well i'm no expert, but i believe its much more complicated than that. first you have to figure out your curent status. do you like it, is there too much oversteer/understeer and in wich phase of the curve. to correct understeer usually means more negative front camber and soften front shocks (stiffen bump.)

here is a list of corrections you can make. In the end its all about balance and what makes you comfortable to push the car hard.

Thats why i'm keeping my suspension pretty basic at the beggining, so i have little variables to mess with (only tyre pressure, front toe, front caster), than i can add parts that allow more adjustability as i learn what i need/want.
