Your just itching to burn a whole in your pocket. All this stuff you ask about for a “street Cruiser” (your words) is point less. Drive it for a year and find some one close that would let you drive their car that has a rack.
I’ve built my car for hard road driving, Auto X and at some point track days, and have all stock style parts with no slop in the steering. When the stock steering and suspension are setup correctly, these cars will handle amazing.
