This is regarding the rear LCA bushing on the ST.

The bigger and more visible one at the rear is primarily tasked with handling acceleration and brake torque reactions and the fore-aft component of pothole strikes. Such a load entering at the ball joint is turned through 90 degrees by the L-shape of the arm so it can be absorbed in the rear bushing as an inward force. Here in the ST this bushing is firmer than the base car because of the ST's much greater acceleration and braking potential and a somewhat lessened need to deliver a plush ride.
