The holes for the rear bar could be much tighter to the bar for a cleaner install.
Questionable how much benefit they actually produce on the CR-Z. These aren't floppy 90's Civics with load bearing strut towers hanging in the breeze.
The front strut towers that are load bearing are tied to the cowl/firewall very tight to the A pillars and the cowl is a massively stiff area. Where the front bar mounts is out on the frame horn a lonnnnnggg ways from where the struts put load on the chassis.
The rear is just a joke. The rear suspension loads are put into the floor of the unibody right into the main frame box sections. Then the IMA cage, spare tire rack, and rear seat back are all very substantial pieces of steel fixed to the floor with very large hardware. There really isn't any flex back there in the body. That aftermarket bar bolts a distance from the rear shock mounts and the rear shocks don't put much of any load on the chassis.
I would skip the weight penalty.
