Trailing arms for a road car?

[LS6 Tommy]

If you access to or can weld, boxing the stock lowers is the best bang for the buck.

Add poly bushings and 95% of wheel hop goes away and the car handles "better".

The wheel hop goes away because the poly bushings bind up the rear suspension. It can't articulate. As for improving handling, a rear suspension that can't move well & follow the road can't possibly turn faster lap times...

AFAIC, poly has no business in a suspension except on A-arms or anti sway bar mounts. 99% of all vehicle manufacturers agree...

I had poly bushings in the arms of the '88 pickup I had (lowered, aftermarket arms) and it squeaked like crazy. I don't remember how often I greased them, but they always squeaked.

As you have discovered, greasing poly is at best a temporary "fix". You'd have much better luck making sure that the poly pucks are a tiny bit shorter than the inner sleeves that go through them. Tiny, as in no more than 1/32" and preferably less.
