There are no roof bows, but I don't think this is significant.

Seriously, EPS is a force feedback software controlled system. The roof has NOTHING to do with this. The steering feedback is artificially created by an electric motor. Or perhaps more accurately I should say that the assist is completely controlled by software, so your entire experience other than the behavior when assist is minimal (like when unwinding) is completely defined by software. Dramatic differences exist if you've tried flashing different EPS settings on an F8x from original software to ZCP or CS.
