I have to say that i like the firm ride given by my set up. It is the stock M Sport suspension for the 1995 540 6 sp. Lowered and firmer. It can seem somewhat more jarring than that plush ride in say a stock 525 where you almost can't feel a thing. This set up though allows for more aggressive maneuvering. It really defeats imperfections in the road surface it has such authority over irregular surfaces. Its not so jarring that you feel you've been in the Ring with Mohamed Ali or George Foreman but there is just no bouncing ,you go over a bump and the car just says "Ha! whammmo,what bump?,how do you like that, give us another one."as you nail that highway merge at 70. its like the wheels are magnetized to the road.What this is a function of i don't know. If they used a certain make shock for this suspension or if its just from having the springs lower but when i get around to replacing my struts and shocks i don't want to substantially change the present ride.
