You using the e24 coilovers from BC?
I have a feeling thats BCs ebay. But FWIW you can buy them directly from BCs website for the same price.

BC Racing is less than an hour away from me too surprisingly. Ive only heard good things about their stuff, granted I believe their kits all came from the same factory in Asia as all the other private label coilover brands.
True, but the ebay link provides free shipping. Don't know about BC Racing directly.
