Is the vehicle lowered? Do you plan on lowering it?
we need to know what your intentions are for the car. is it only a daily driver? is it a drag racing car? is it an autocross/road race car?
as a stock-height daily driver, no.
as a stock-height drag car, maybe not, but they could benefit you.
as a stock-height auto-x/road race car, no.
as a lowered car for any purpose, they are recommended, but depending on the application, not absolutely "required".
