I don't use a harness bar in my Z06...but, I feel the effort to stay in the
seat is a good aerobic workout, so what the heck...
On the other hand, you can lock the lap belt, by pulling all the way out
until it starts "clicking" on retraction. Cinch it down tight and then move the
seat forward a little and you're in pretty good shape.

Driving without one teaches you to be smoother, by making it freaking hard
to hold on if yer not. Don't ya just love the stock Z06 seats.
