Even if you do not add any bracing, or sway bar in the back, and just increase the spring rate, and matching damper valving rate, whether part of a coil over system, or factory style replacements of the rear suspension (as I plan to do, since high rate sway bars/added beam axle braces in the back can actually become dangerous when driving on gravel/dirt), these plates will help quell excessive lift off oversteer.
