Hi Guys,I have the above car with standard suspension. I have 18" wheels on it now which looks too high. I looked at the S'line springs but they cost quite a bit like double of eibach pro kit. Does the eibach pro kit drop the same amount as sline 30mm or more? I don't want more or much more as I like the s'line height.Is the spring quality of the eibachs as good as the oem sline?Also should I change the shocks too ? to sachs oem slines?My car has done 90000kms.And what do you guys do to your xenons once lowered?Thanks,K.
