just a quick question I have the eibach pro kit springs installed in the front of my car and like them but ive never installed the rear. I was wondering if I installed the rear spring without the relocation lca and adjustable pan hard bar if I could take it for a drive to see how they feel before I purchase the new adj panhard bar and relocation lca?

 

Sure can, my friend has had a set on his Camaro for 5 or 6 years and has yet to buy a ajustable Panhard bar.

 

the adjustable PHB is only necessary if your axle is not centered, and it's not rare for them to be off 1/4" or so from the factory, it's not a critical thing, it's mostly important for appearances and to fit big tires in there without hitting on one side.

relo brackets are in no way a requirement, and the pro-kit rear springs may not lower the car enough for them to even be an advantage

 

ive been holding off putting the springs off for 2 years cause I didn't want to buy more parts.
