You should always do an alignment if you change the ride height.Does anything need to be recalibrated if the 1.5 collars are added. I have them on my 18 now but I am picking up my 23 today an am considering putting them on it. I did not have to do an alignment on my 18 nor did I adjust the headlights, although I do get flashed from time to time.
