Eiback Pro kit vs Ford Racing Lowering Spring kit.

Ford seems cheaper. Is there a reason to prefer Eiback over Ford? Do they lower the same amount? Both seem to have a progressive spring rate, which I'd like to keep the everyday drive fairly smooth.

 

I don't know personally, I'm just passing on info I have seen posted here many, many times: the Ford Racing springs are just re-badged Eibachs.

 

Having been in Eibach's manufacturing facility here in SoCal, I can say for 100% sure that the Eibach Pro Kit and FRPP springs are one and the same.
