280z4me2 Posted August 13, 2012 Share Posted August 13, 2012 I found cosmos springs in ebay a few months back but they were installed on the stock spring perch. Just came across these that look better but have dual springs. Anyone messed with these? http://item.mobileweb.ebay.com/viewitem?itemId=261078590483&cmd=VIDESC&index=1&nav=SEARCH&nid=85153080861 Quote Link to comment Share on other sites More sharing options...
zero Posted August 13, 2012 Share Posted August 13, 2012 I had them. The spring rates are very high. Sleeves are sleeves as far as I'm concerned, but I ended up ordering some 10" springs in 225/250lbin rates. Quote Link to comment Share on other sites More sharing options...
280z4me2 Posted August 13, 2012 Author Share Posted August 13, 2012 All street driving for me. Was it just uncomfortably stiff for you? Did you have the duel spring just like that one and swapped it out for single 10"? What shocks did you run? Quote Link to comment Share on other sites More sharing options...
zero Posted August 13, 2012 Share Posted August 13, 2012 Yeah I had the dual spring. The secondary spring is really just there to keep the pretty short main spring on from rattling when the suspension droops. The coils were pretty much bound at ride height. I was on the street as well, it was really too stiff at least for me. Certainly too stiff for the Tokico HP's I was running. Now I'm running illumina's on sectioned struts with single 10" springs using those sleeves. Quote Link to comment Share on other sites More sharing options...
280z4me2 Posted August 13, 2012 Author Share Posted August 13, 2012 Do you have a 280? If so, did you have to bore the sleeves to fit? Quote Link to comment Share on other sites More sharing options...
zero Posted August 13, 2012 Share Posted August 13, 2012 240z, so no Quote Link to comment Share on other sites More sharing options...
