i just bought eibach lowering springs (6040.140) today.
eibach's website and other website say the fitment excludes the ES...I was getting all four for a steal...$75!!! lol
so i called eibach customer service and they said they should still fit and its a typo on their part because they never tested them on the ES when they originally released.
so i bought them. anyways me and my buddy plan on putting them on the end of this week or sometime next week so ill try to keep you updated on how it goes.
