As the car cornered the weight swung to the opposite flank effectively leveling the vehicle on the cheap. The springs re-centered it on the straights. Spring helpers are the same inexpensive way of full-time ironing out the vehicle vibrations and undulations. You should renew yours today and see the difference.
this makes sense.. I put a set in my vx that was 1/2 height. the ride is definitely less jarring, but not as smooth. I'm noticing a lot more small vibrations from driving on what used to feel like smooth roads. however going over train tracks and the horrible streets around my neighborhood, the ride is much smoother

back on the highway today, so that will be my deciding factor whether the modified ones stay or go
