try using some thick ass HYDRALIC OIL (not diff oil/ used engine oil etc etc)
in my manual it says the shockers are filled with dexron 2 (atf oil)
drain the oil out the struts, fill with thick oil and let me know how it goes,
as for the eb springs, (i have a topic comapiring them both) eb and ke30 springs are the same width BUT the ke30 spring seams to be lots softer than the eb coils. i could compress the ke30 springs 4cm with my hands but only 1 cm with the eb?
