yng_750 247 Report post Posted November 5, 2014 Bit of a weird one. Ive been told 3 series springs will fit another application im looking at but im not sure which springs they are talking about other than they are 6 cyl springs. So does any have or can take measurments for e30 and e36 springs. Need diameter top. Diameter bottom. Free length. And if possible spring rate and length of spring compressed on struts. Any help much appreciated. Quote Share this post Link to post Share on other sites
