A friend of mine is going to sell me a set of koni adjustable coil overs. But the thing is i can't find any info at all about them. They came off a parts car and the only reason i'm looking at getting them is cause my struts are shot. The numbers i have found and can read are the following. On the front struts the number is 3507022 and on the front springs 22201310. And on the rear struts the only number i could find is 82101162. I've been looking for about an hour or so trying to find anything about these. I know they are used and unfortunately look kind of old. But if he's going to sell them to me for cheap, might as well. Any help would be great. He's asking $400 for them, but i'm prob counter offer like $250 maybe $300
