Front backspace 17*8 on dart, final advice before buying

To run bigger tires, your sway bar concerns me a little it looks awfully close. I purchased a new hellwig sway bar, that is bent back farther to allow for higher backspace rims. From what ive read the best backspace number for wider tires, is a custom number of some amount but its different for every car. Most people try and compromise and get something premade instead of custom though cause its a lot cheaper. For clearance im fine around the fenders and sway bar, im close to the tie rods but they still dont touch so i dont worry about it.
