RE: [T3] The safety FAQ

<x-charset iso-8859-1>>From my Type 2 ownership experience, I can also add a bit of description
about how Volkswagen felt a factory sunroof affected the rigidity of its
body.  Volkswagen added large underside plates to reinforce the body as well
as adding significant amounts of structural reinforcement to the roof area.
If you have not seen a sunroof Kombi--which has an exposed metal
headliner--look at a 1968-1972 Westy with it's interior removed.  Since the
Westy and the sunroof busses used the same structure, they both have the
extra bracing.

In short, sunroofs are cool and I love them, but if they are not engineered
properly, can adversely affect the structure they are added to.

The convertible Beetles DID come with a greatly beefed-up pan in
the rocker area, however, to replace the stiffness which
disappeared with the roof.

I don't think most people appreciate how much stiffness the intact
roof, with the internal stiffening ribs, really contributes. Leaving the
door frame above the door intact, as I believe you've done, helps a
lot, but there's still a penalty.
