I dont have any of those symptoms but was wondering if its a good "precautionary" measure to put them in before the alignment or if they will help in drivability in any other way.
I drove mine for 3-4 weeks after the "Steeda Sport" install and just got it re-aligned yesterday. It only needed a slight adjustment...but i definetly would get it re-alligned if you haven't already. Everything seemed ok with mine until 100mph , it had a slight shake in the wheel.
