just got in from the garage and figured i would put something up and see if anyones come across this while working on there rear suspension on there drag cars .i realise this may be difficult to visualise without some pictures .but can add some later if needed.
I'm swapping over to a bus box and of course at the same time doing the IRS conversion from swing .
i have made a trailing arm jig for final arm construction as well as a test trailing arm prenarrowed 1" that allows me to start doing some on car fitting .the test trailing arm is also adjustable to allow the bearing housing to float and can be moved in or out so there is a total of 3" of adjustability for wheel position .
got the test arm in and the wheel mounted and noticed it actual works , nice .
BUT what I'm after is the ability to actually lower the cars rear stance 1-1.5 " .i figured since i have irs and a flatter wheel contact i will jack it up and see how high i can get it to go .now i know why people raise the rear torsion housings .what happens is the spring plate hits the top stop of the torsion housing and stops upward travel .this is also the position i would like the rear wheel to sit / start from not end at
options are
- mount the bearing Assembly 2 " up and refab the arm assembles to accommodate and leave basic geometry stock
- leave spring plates and stop alone and mount new trailing arms at a angle onto the springplates say with a 15 deg dogleg idea
- notch the spring plate to allow more space before hitting the torsion housing stop
- trim the torsion housing stop to allow more springplate upward travel
if anyone has some advise or has come across this i would love to hear from you
