Ah i see now, sorry for my inexperience ive been thinking all along that you were refering to an eibach pro kit for a slk320 not the stock eibach Springs from a slk 32 Amg, hehehe, i ve been looking around the internet for info on the spring rates for those and couldnt find any numbers but if they are anywere between my current eibachs (progressive) and the stock srt6 then i would gladly take them from you, can you quote me how much its going to be shipping them to 92173?
