All I can say is my car is soo much more enjoyable to drive since I installed my offset bushings. Tracks much nicer on the hyway and centers nice when letting go of the steering wheel.
Yes maybe something changed from the last alignment but I don't think so (I use the same guy). If OP installs them correctly I don't think he will regret doing so. I do like the tubular arms but being frugal and having stock arms in great shape I'll spend my money elsewhere. JMO
