Consider doing all 8 at once, and never worry about it again for another 100k.

Since an alignment is needed when changing tie rods, we highly recommend at least doing both sides together.

What are the advantages of the aluminum kit? Obviously they should be lighter, but are they more resilient and less prone to breaking early?
