It's normal, the stiffer spring rate requires that the free length be considerably shorter than the stock springs.

Install them and enjoy the better handling and lower ride height.

Default Spring direction - confusion

Does anyone have a answer to this question? We pulled the stock springs off some time ago and have installed eibach springs letter side up per manufacturer, but the originals had the flat end of spring nested in the upper control arm.
We also have read several posts that would lead us to believe the flat goes on the bottom or lower control arm - and we have viewed a couple videos that appeared to show the flatter end or closer coil end going into the top control arm?
