I have the full rubber bushings on my car. I believe they are the m3 bushings. There will be no alignment required since only toe is adjustable.
If you get the off set bushings they give you a better camber for turning.
I wouldnt go with urathane bushings, some might say different but I think they give a harder ride.
And if you want to spend 600$ m3 aluminum arms are always a plus.
