Recently replaced all my shocks and springs including rubbers. Drove a few hundred kilometers until everything settled and then did an alignment at the garage. Wasn't too happy with the way the zed sits on the rear therefore I wanted to replace the rear spring pads with 33531094754 which is 9mm thicker than the current rear spring pad (form 5mm to 14mm rubber). Would i need an alignment again if I just swap the rear spring pad or it shouldn't make too much of a difference?
