I know they offer front and rear strut tower braces, and ive seen a few people have full roll cages, but has anyone made any braces for under the car? Ive read around here that the w-body is decently stiff from the factory? Maybe its because my rocker panel's are pretty much gone but I feel it could use some improvement.

I know it's a 16 year old gm product, and im being super picky, but I cant be the ONLY one right?
