Both are roughly the same cost. Is there any reason to pick one over the other?

 

What's up man,

So I have purchased a handful of things from z1 in the last few months and Rods been the dude helping me out. He was telling me that the z1 control arms have a connection that makes it easy to regrease the bushings with a grease gun. I also think they offer 2 different styles. I would just email or call, they enjoy hearing about your car.
