Valid point. I do know however that rear strut braces worked wonders in the VW GTIs/Golfs/Rabbits (albeit hatchbacks) that all my buddies used to drive in highschool. I would have to think that it would add some sort of structural rigidity. Enough to notice? Probably not, but every little bit helps.6104696 said:Would it actually do anything? A strut tower brace makes sense in the front where you have no "floor" and no roof to provide stiffness; but in the back you have like the whole rest of the car (trunk floor, roof, etc. etc etc......). Isn't that supposed to be one of the strong points of the sigma chassis?
