I've read a lot of post about the Eibach Pro Kit, and that it lowers 1.25". And i have a few questions. How much do they cost for a 2004 coupe. Do I need any other mods to make it work? Will it rub anything with stock tires? What are the advantages and disadvantages of it?

Also will the kit for the SLK230K/SLK320 9/96-04 work? There's an $80 difference from MB to Crossfire.

Also, these are the cheapest i found, but it says "Note: Avg low 1.0"F 1.2"R
NOTE: Requires the rear bump - stops to be trimmed by 20mm."
