We are having a terminology problem here. Are you trying to prevent flex, where the chassis distorts but returns to original position after force is removed, or are you trying to prevent bending, where the chassis distorts and remains in that new position after force is removed?

A bolt-in cage won't provide much chassis stiffness. When I say bolt-in, I picture a four-point cage with pads in the front footwells and behind the front seats that is allowed by SCCA for street cars.

A welded-in cage can significantly increase stiffness because you can make a 6-point cage that attaches to the rear strut towers. Even better, an 8-point cage with tie-ins to the fire-wall.

Yes, the Sentra is a flexi-flyer when it comes to road racing.
