Do I need trailing arms on my custom IRS chassis?

[65_LS1_T56]

I'm seeing it needs more direct attachment to the frame (the center section). Right now, it looks as if it is "hanging" only from the frame. You have to imagine all of the twisting force that a rear sees, live axle or independent. To me, I think you need a whole other "cradle" that the rear kind of sits in as well as the upper attachment you currently have. Maybe you have plans for that, but not shown yet.

Also, most independent style rears would have a toe link too. Unless you are going for something like the Heidts system. Notice the "trailing arms" on theirs and the cradle under the center section.


Also, how do you adjust for caster?
Fab work looks great.
