i have a set of used eibach pro kit springs. they were used for less than 2 months. they were on my roomates car. he used them for about 6 or 7 weeks before he went with coilovers.
This was at a regular shop here in houston. I got the part number out of an Orilley's catalog my coworker has. They list in the catalog for $249 or $269. I agreed to pay $249 but when I got there to pick them up and pay the guy at the counter said, I quote, I quoted you $139 right?", and of course said yes. Ater tax it added to $151.
