    IRS WHEEL TRAMP, CONTINUED

    Stay tuned for the YouTube videos, just trying to do it without getting 500 comments from non-engineers! I hope to take more GoPro of the current, generally well tied down irs. Still trying to adapt a damper to the hubs and would ideally like to dampen the diff. Solid cradle mounts give no...

    M4v video files on this forum do not seem to work! Can someone suggest how to post videos here? They work fine one my iPad and on a windows 10 laptop, but not when posted via this forum. I will explore photobucket. Pity as they are very good tramp videos.

    another one for the rear suspension to see what part moveshttps://files.engineering.com/getfile.aspx?folder=849baea7-52bb-45bf-8728-7e3e981edbf1&file=Tramp_rear_upper_no_shocker.m4v

    I see that the forum only allows one video or photo link at a time!!https://files.engineering.com/getfile.aspx?folder=ca3e5a52-8f9f-48b7-98c5-77b90c946907&file=Tramp_Diff.m4v

    Hi to Greg and others, I have attached a go-pro video comprising a few shots of various drivetrain pieces tramping showing a VE Commodore suspension as it tramps. Of note is the engine bay, first as standard, (note how the steering fluid aerates) then engine bay with the addition of a damper; a...

    BOB, your trailing arm bracket looks slightly different. The photo link of mine shows the original trailing arm and toe rod, before I cleaned it! Note the top part of the bracket. Looks suspect. The original TA has a very soft rubber bush and when tramping this bush obviously will flex...

    Bob, I will try to figure out how to send GoPro vision to this forum as it really is fantastic, especially the diff and the wheel tramping. My setup is the same with the exception that the lower rear arm that contains the strut is rubber mounted to the hub whereas your s is a letter version...

    The attach photo link shows a simple diff bracket to suit a BMW. The link to a description is https://bmw.spoolstreet.com/threads/clark-performance-fabrication-diff-lockdown-install-on-dct.2478/ Not sure of long term use, but hey, don’t knock it as there are plenty of BMW owners that say it...

    Buggar, well done, nice to know I’m not Robinson Crusoe after all. I have solid cradle mounts and found that of course movement in the cradle is zero. I too rethink the cradle is over designed and did contemplate (for 30 seconds) making up a complete rear tubular cradle mainly to mount the...

    Thankyou to Cibachrome, Norm and Greg for the type of replies that I was seeking initially from an engineering forum. Greg, GM invested huge dollars in seeking a solution, as did the others, way more than you suggested and still came up short. I suspect that they ran out of ideas rather than...

    Norm, thanks for the modelling reference. I presume the main manufacturers have access to the same or similar models. The outcome is that their IRS cars all seem to tramp, so does this mean the models are of no help, or perhaps other factors like cost override. I see no value in this model in...

    Getting near the end of asking this forum for help on this topic. “Cibachrome” could you please have another go at explaining what you mean re tyre design. The VE Commodore and the Camaro were both designed in Melbourne to use very grippy Bridgestone Pontenza 050 tyres. I don’t like low...

    GRUNTGURU, the diff has two mounts in the front and one in the rear offset inline with the crown wheel. “Gopro” videos are fantastic as the diff climbs as per the pinion climbing the crown wheel then as resonance occurs it pivots madly about the rear mount. “Snubbers” or a long arm connecting...

    I have tried to attach a file of the layout of a Camaro and hope it can be seen, albeit modified by BMR with links shown in red. (I hope the picture is attached!!). Greg and others, it is not the more simple Omega layout, and has upper and lower links that pretend to be wishbones. As you can...
