thinking about getting a set. It seems cheaper to buy them 1 at a time. are they interchangeable as to rh/lh or do they have a particular side orientation? thanks.

 

They can go to either side. Unless you have upgraded your springs, I won't install them right away. They are matched for the spring rate on the Cobra and wouldn't really do anything to add performance to your car.

 

I have eibachs pro line kit. those would be better than the monroes I have now though huh?

 

Yes.
