Before we get into layout of the ideal suspension ( no such thing) ..lets look at the double wishbone layouts.
Equal length and parallel links - this is the hot set up- minimal camber change but..the track width changes. Note the change when using short lengths. The longer links still change the track width..though minimal..the whole draw back is the width of the race car and this set up is real hard ( if not impossible ) with front engine stock car...there is just no room. Note the Roll Center and location. The min camber, and the camber build and track width change during roll plus bump and RC location/ height is my reason for thinking that this is the hot set up. my opinion..
