I'm thinking of installing a Hardbar harness bar on my C6Z. But I'm wondering if the bar interferes with the stock seat travel or seatback position in any way?

Any other disadvantages on a street car? I don't mean for using it on the street, I mean for having it installed. I would want to continue using the stock belts on the street.

Yes. You need the Hardbar extender. View their website at:
