I'm on UPR/Eibach Pro springs which are made by Eibach to the same spec as Eibach Pro Kit springs. I've very happy with them. They work well, and Eibach offers their "Million Mile Warranty." That's nice peace of mind.
I'll post here again after I install them, had a set back as I need an adjustable upper control arm for this
setup. I'm only installing the rear springs to see how that works 1st. Research tells me
I don't need the uca if I have the Whiteline relocation brackets, which I do so I'll be
installing the Stack Racing springs sooner.
