so should i drop the gears in first and then lower it with eibachs' pro-kit or lower it and drop the gears in? will the drop affect the pinion angle to the point where it would have to be redone if i put the gears in first?

 

i think you should be fine man i plan on putting the pro kit on too soon im just waiting for shocks and struts first

 

do both then check your pinion angle. Then save up and buy adj. control arms if needed.I have Pros..did gear change..alls fine..
