  werkz.com: Miata Roll Bar Install
I noticed that other roll bars would put a cross brace in between the sides of the hoop, but this prevented the seat from being reclined all the way.
You cannot expect a roll bar welded to the chassis to survive an incident.
The problem is that the roll bar will transfer huge loads into it's mounts, and the thin sheetmetal in a car will quickly punch through or tear away.

 Anti Roll Bar tech
An anti-roll bar affects the roll stiffness of the suspension to which it's attached, which determines the percentage of the total cornering load that will be supported by that end or the car.
If the suspension on one side is compressed (as occurs due to body roll during cornering), the lever arm on that side twists the main length of the anti-roll bar and tries to compress the suspension on the other side of the car.
The extent to which the anti-roll bar increases roll stiffness is dependent on the stiffness of the anti-roll bar itself and where it attaches to the suspension.

 Brey-Krause Boxster Roll Bar Extension
The B-K roll bar extension kit consists of the wide u-shaped bar, two connecting bracket plates for the sides (each attached with two small hex bolts and lock nuts), and two brackets for the tops of the roll bar hoops (each attached with two large hex bolts).
Just remove the roll hoop trim, stick the protector tape on, install the side attachment brackets onto the shoulder belt mounts, put the extension in place, and finally attach the 8 bolts that connect the extension to the side attachment brackes and the roll bar hoops.
It's worth noting that the Boxster's factory roll bar is a four-point roll bar—although it's not obvious from outside the car, the roll bar actually consists of two full-width welded pieces which spread the load onto four separate footings on the frame.

 Anti-roll Bar   (Site not responding. Last check: 2007-10-15)
Fitting a stiffer anti roll bar to cars with independent front suspension and a solid rear axle, the tendency is often towards less understeer.
The reason is, the stiffer, or in Bob's case the presence of a roll bar, prevents excessive positive camber, which loses traction, and causes understeer in the front tyres in a turn (quite easy to spot in the photo above),.
The antiroll bar is held on to the car by the original mounts (painted red) and the jubilee clips stop the bar moving sideways.
