I got these used from a guy who said they were marked, and I cant find any markings on them. I am guessing maybe they are progressive rate, because the top coils are 3/8" and the bottom ones are 1/2". They are 13" tall, and have eight coils. From the color of them, I would say Eibach, but I want to be sure they are drag springs and not lowering springs before I put them in the car. Thanks for any help you can offer.
