Hello. I recently had trouble with a mechanically incompatible door strut that I purchased from a well known, and otherwise respected vendor. I've since ordered replacement struts from a different vendor, and will be comparing them in terms of geometry and function. I'm considering expanding the scope into something more comprehensive, if enough non-vendor list members are interested. If you would like such a strut comparison test done, email me directly. If eight or more people are interested, I'll run the test, and publish the results. If less than eight people are interested, I probably won't bother. I don't really have anything to prove. I'm highly interested in getting hold of an NOS (New Old Stock) original equipement Stabilus Lift-o-mat strut to measure as a baseline. Though I question the relevance of data from a twenty year old part, I'd like to gather the data for reference. I realize a strut of this vintage has great Concours value, so I assure you that it will be treated with care, cycled only once, and returned in good condition. If you are willing to lend me one, please email me directly. I'm also interested in getting some samples of used struts of known origin, to compare the new state to the end-of-life state. It also occured to me that there's no reason that the test couldn't be expanded to include struts from multiple vendors. I invite any vendor who wishes to submit a sample strut for comparison. Email me for shipping info. I will accept, without prejudice, the first eight vendor entries for testing. The only term is that this is a "No Whining" event. If you wish to participate, you waive any right to complain about the results. Testing will include: Extended length Compressed length Travel distance Force at extended length Force at compressed length Testing might include: Force at intermediate points between extended and compressed states Force versus temperature, 20degreesF to 150degreesF (NOS Stabilus strut, if tested, would not be temperature cycled) Testing will not include: Dynamic testing Damping (I wish I could, as I think this is important, but a dynamic test setup will take more time and money than I wish to spend on the test) I feel a test of this type can benefit the Delorean community. Either we'll find out that they're all pretty much the same, and we don't have to worry, or we'll find out that one strut is distinctly better than the other, which is also a nice thing to know. Non-vendors, email me if you want me to run this test. Vendors, step on up to the plate. Rick Gendreau
