I was just curious if I'm feeling the same ride as everyone else. I installed the H&R springs on my 2013 SHO a little over a month ago, and now that all the springs have settled in, my ride is MUCH rougher, which I expected, and also have no problem with. Also, when I installed the fronts with the car still on the lift, the springs just sit in there loose until you drop it? The fronts just seem to be a little low in my opinion, I have to be careful when like going over a decent hump to go slow or the fronts will rub the top of the wheel well when the car comes down, is this normal?
