JMortensen Posted January 4, 2005 Share Posted January 4, 2005 http://forums.hybridz.org/showthread.php?t=87758 There's the thread if anyone wants to read it again. I don't know how modified these suspensions were. Sounded like some were bone stock, some were raced, some in between. The point was more that the stock setup has it's weak points, and the TC buckets separating from the frame due to heims joints without bushings seems at best a minimal concern when weighed against the stock TC rod breaking in half because of poly bushings.

Owen Posted January 4, 2005 Share Posted January 4, 2005 If I ever do something like this I plan on using Mike Kelley's design, which uses the out board side of the stock LCA and the stock mounts of the TC rods. One thing about the sway bar mounting, how is it mounted in the BMW previously linked? Is it mounted to the strut tube? Owen Quote Link to comment Share on other sites More sharing options...
Owen Posted January 4, 2005 Share Posted January 4, 2005 And where do people get those cone shaped spacers? On the inboard side of the LCA in the above pic. Owen Quote Link to comment Share on other sites More sharing options...

blueovalz Posted January 5, 2005 Share Posted January 5, 2005 This is true. The OEM location is off the side of the strut tube. It allows a longer link which promotes the use of an adjustable bar without getting into large link angles. Neat design. Quote Link to comment Share on other sites More sharing options...
Owen Posted January 5, 2005 Share Posted January 5, 2005 I did some checking and I think it's actually mounted off a little metal tab on the body rather than the strut. Shouldn't be too hard to do on a Z, just make it strong enough. This should solve the concern about the bending of the threaded adjuster of the adjustable control arms?

JMortensen Posted January 5, 2005 Share Posted January 5, 2005 That don't make no sense Owen. If the sway bar is connected to the frame and the end links are connected to the body, then it does nothing. It has to connect to the suspsension somewhere. I've worked on a couple 3 series and the BMW end links are very long and they attach to a tab that sticks off the strut. Terry is right, the advantage is that the end link doesn't get tweaked even under full compression or extension. It really is a better design.

Owen Posted January 5, 2005 Share Posted January 5, 2005 Yeah, that makes sense...so I guess what I was reading is that the metal tab on the strut housing breaks off when undergoing forces of a larger bar. Owen Quote Link to comment Share on other sites More sharing options...
peej410 Posted January 5, 2005 Share Posted January 5, 2005 someone design it and ill make a prototype, im not working now and i have free time and i want to have something besides garage burnout videos and rollcage pictures to offer the hybridz community ooo and check out my new photos http://pg.photos.yahoo.com/ph/peej410/album?.dir=b912 to see if you guys think im capable of doing this Quote Link to comment Share on other sites More sharing options...
johnc Posted January 5, 2005 Share Posted January 5, 2005 Owen, Where did you get that picture of the LCA on a BMW? I'm surprised that someone would mount an LCA in single shear. Quote Link to comment Share on other sites More sharing options...
TimZ Posted January 5, 2005 Share Posted January 5, 2005 Owen' date=' Where did you get that picture of the LCA on a BMW? I'm surprised that someone would mount an LCA in single shear.[/quote'] It was from the link that was posted above - they claimed that this was the same arrangement as stock, which I was even more surprised at, seeing as how that piece was for a BMW.

johnc Posted January 5, 2005 Share Posted January 5, 2005 I just crawled under an E36 BMW and yes, the front LCA is in single shear through a ball joint. Go figure... Quote Link to comment Share on other sites More sharing options...
blueovalz Posted January 6, 2005 Share Posted January 6, 2005 Define "single shear" please (looking for enlightenment). Quote Link to comment Share on other sites More sharing options...
johnc Posted January 6, 2005 Share Posted January 6, 2005 "Single shear" defines a connection where the connecting bolt, pin, pivot, etc. is only connected to the frame, crossmember, beam, etc. on one side. The LCA connection on the BMW pictured above is a bolt that passes through the LCA and is threaded into the crossmember. The stock 240Z front LCA connection at the crossmember is "double shear" because the bolt passes through the crossmember, through the LCA, and through the crossmember again. Single shear connections are generally thought of as weaker then a double shear connection. But a properly engineered single shear connection can be strong enough.
