I am working on my front and rear track width plan

I will be using a mustang II front suspension set up from speedway motors
using the Narrowed arms 56.75 in hub to hub, with wilwood vented rotors.
My body front fender center to front center fender is 52 inch. have not built the inner fender walls. will be using 15 in wheels. I need help with back set width size of wheels. wheel width 7.5 .

I will be using a solid 9 inch ford rear end assembly with vented rotors.
Planning on track width of 54 in . I am thinking straight about this?? size of wheels 15X8

I have read that rear track width should be narrower than the front for road racing applications.
