Bumpstops for axle?
For those of you with live back ends, have you used any sort of bumpstop? I am concerned that in droop (ie hump back bridges etc!) then the axle might
hit the chassis rail, and take out my handbrake cables at the same time! I was thinking of using some thick silicone gasket material I have to act as
a bit of a bumpstop.... What have others done?

the bumpstops are in the shocks, i would be seriously worried if the axle came into contact with the chassis, you would end up in a ditch

Two choices in droop
Cut some webbing, an old seat belt and have a loop from above to arrest the fall
On the bit of metal it may hit drop on a bit of rubber.
As above usually the shock will run out of travel before its an issue

I thought of this when building mine but it was unnecessary, but I would have used rubber boat trailer guides (exactly the right shape)
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

The best way of limiting droop is with seat belt webbing. The two main advantages are:
1 You can "adjust" the droop, and
2 Perhaps most importantly, you can choose where the loading is taken on the chassis. If you simply let the axle drop down onto the chassis, this will
probably not be in the best place to avoid damage, bent tubes etc.
Strictly speaking, the shock should limit the droop but using "droop straps" is also kinder to the shocks. Not all shocks have internal
bumpstops and even those that do do not take kindly to repeated abuse. Even an Ohlins will fail if it is continually and violently topping out. The
internal bumpstop eventually falls apart and the shock will stop working due to all the debris inside.

Landrovers use the webbing stops. Britpart sell them (you may need to find a britpart dealer - such as my mate - Specialist 4X4 services).
