actually the post wasn't directed to you but rather the op.

if you look closer you'll see this:

Porsche Boxster (986) Middle Lower Bar / Middle Member Brace - Ultra Racing Product Catalog

which appears to strengthen the centre tunnel - a source of the flex.

I've seen all of those products. I thought you mentioned something new that is essentially an X brace that goes under the carpet and strengthens the mid section?

Since my car's on jackstands as I type I'm going to use some flat 2* .25" wide aluminum to make a strap utilizing the 2 bolts already there to tie the center of the 'transmission' tunnel together. My main concern is the point at either end of the floor pan. I think the majority of forces push through the suspension in an upwardly direction and the lack of a roof creates flex. An 8 point cage counteracts these by directing them to the other end through the cage. Without that we have hinge- like flex points - no?
So, strut tower to floor, floor to strut tower. Or, next best thing- cowl to floor, floor to rr bulkhead? I want to trianglate these right angles.
