I ordered some off of ebay, basically no-name brand and if you look carefully, you'll see that a lot of ebay sellers get a whole bunch made and sell them as if they could fit on all cars, i got screwed bad. they sent me coilovers for a honda civic. they do not fit on stock struts. Id cancle the transaction as soon as possible if it is the same kind im talking about.

check that link out, if it resembles those, then check out the sellers other items to see that they sell the same product for many differant cars. doesnt make sence.
