A friend of mine just bought a Focus from his mechanic who sells cars on the side. He said it was a lowrider, and the mechanic put the stock parts back on, so I talked to the mechanic about the 'lowrider suspension' parts he took off.
He said that it had front struts and springs, and they had a height adjustment. He also said they had an Eibach tag on them. The rears are (as far as he can tell) chopped stock rear springs. He wants $100 for the whole setup.
as far as I know, eibach never made an adjustable height spring. All I can think of, is it must have had eiback struts with those ebay 'coilovers'
