My spring was green color also that came off the bmw.
I put the new spring (Suplex HD) besides my old spring (cracked at the very bottom) and they were on par height wise.
Not sure why you weren't able to put the spring in? I just undid my lower shock and pressed down on the brake disc old one popped off with a little wiggle using a crowbar. To get the new one in I just placed the bottom part of the spring in and then used the crowbar again to pry it in.
I saw another couple of guys talking about using the same spring on their XI's. I also had a thread about a week ago or so on here with the same question and they told me that's the one.
