I just read this from somebody that installed them -
"There is definitely more chassis vibration. my steering wheel doesn't shake, my pedals don't shake but you can feel it in your butt if that makes sense. almost as if your rear tires are really out of balance but for the front of the car. i drove the car on many diff types of roads. driving slower on bad roads, the car feels rough, stiff, more interior rattle , the usual road imperfections i usually drive on feel much more harsh when hitting them. little imperfections feel more dramatic...a lot more."
Be interesting to see what you pioneers think after install, but for me, I really don't want to compromise the ride.
