You dont need a strut tower brace, this car has a real frame, no cheesy unibody w/ macpherson strut set-up. Besides,where are you going to bolt it to, the plastic inner fenders? As far as under bracing goes, I could see making one to better link the lower control arm mounting points in the rear together but I dont know if would better than the stock one. On the subject of camber plates, they wouldnt do anything seeing as it has a frame and the upper mounting points for the struts have no effect on alignment, besides, there is alot of camber adjustment in the suspension anyways.
