Autopower's "street" roll bar will look like the "tension gauge set"... except the diagonal bars will point straight down from the roof to the strut towers instead of following the curve of the roof and rear window. This is a much stronger design, but it obviously kills rear seat head space. A "race" roll bar will have a diagonal brace across the main hoop.
The "tension gauge set" doesn't include the floor bar, by the way, it's just there in the picture.
