MrLightning said:Ive always found it interesting, so many people spend time making these aftermarket X braces and putting them in places (behind back seat, radiator support, monte carlo area) and find it as not being much more than somebody who is reinforcing areas that are not overly prone to flexing with respect to noticeable need to do so. Im only stating this as an observation that quite a few people have done. Ive not heard much as to its overall positive affects in changing much, unless its clearly obvious that your engine size and related torque produced is significantly bigger than even mildly built engines, so as to make the argument that the BIG HP, TORQUE motors are flexing areas on the car enough to warrant a need for bracing. Am I just seeing this all wrong, or is it that some people just like to do it for the sake of doing it? Just my observation, and no other reason for my post.
The rear seat braces along with the number 5 body bushings cut down on the rear pillar flex which causes roof/quarter seam cracks on the exterior. Every G body should have came with them and all probably need them, even those with base V6s. My 231 V6 still had enough power to flex the rear pillars enough to crack the roof seams. For the rear seat brace to work its best, you need to have the number 5 body bushing installed (many base models don't have the #5), and the rear seat brace should be welded in to prevent any movement and oblonging that fasteners would have.
