Can 24 inch rims fit a BMW 740il if so what mods do i need to do?

Yes, 24-inch rims can fit a BMW 740iL, but significant modifications are usually required. You will likely need to adjust the suspension, possibly lowering it to prevent rubbing, and you may need to roll or modify the fenders for clearance. Additionally, ensure that the tires are appropriately sized to maintain proper handling and avoid any mechanical issues. Be mindful that larger wheels can affect ride quality and performance.
