Hello, I'm planning to build up an old Impreza L(just for fun, and some autocrossing), and trying to decide what chassis to go with. How does the wagon chassis compare stiffness wise to the sedan(I'm not considering the coupe). I'd like the added utility of the wagon, and depending on the mood I'm in I sometimes prefer the looks of the wagon. Of course if I did go the wagon route, I'd get a rear strut bar to help it out. So how does the chassis stiffness compare? If there isn't much to be lost with the wagon, I'll probably go with it. Thanks.
