IFS front track width questions

[Desert1957]

Been searching for an IFS front kit, stumbled on a kit where they gave you a choice between front track widths. I guess they are changing it with control arm length.

Here are some questions to everyone who has IFS.

1.What looks the best.
2.Can this choice change if you need spacers.
3.If using the stock frame,what is the track width to the center of the tire?

Thanks for any input. I like this look , just trying to figure out how to get there.
