They may do but you may or may not be able to hear it over tyre noise at speed.

If you can hear it to the point of it annoying you, you can spiral some wire on the tubes perpendicular to travel to minimise the noise. Use wire of 1 to 2mm diameter, with 10-15cm spiral spacing (ideally 5 x tube diameter).

This is what the std front mounts that sit inside the front wings look like:

Thanks for the pics mate....I was wondering how the cage mounted through the body and I can clearly see the body is sandwiched between the cage and frame mounts in the process. Understandable given the Defender is not isolation mounted to the chassis but bolted directly to it.

Might be an idea to speak with an approved engineer prior to putting down any cash.. anything decent is going to be chassis mounted.

Being an external cage the involvement of a engineers report and inspection is basically negated. Its no different for registration purposes to a heavy duty roof rack and side brush guards/side steps. That said, yes any internal roll over protection should have a engineer involved from the outset, I have done it numerous times with rally cars, your advice is spot on.


My question stemmed from a comment found out of a Expedition Portal thread.....awesome 130 CC

SD cages are such a treat to install. Do you still have to cut large rectangular holes in the body work for the mating flange to poke up through on the new cages

Yepp, but if you´ve done it before it´s pretty straight forward and everything aligns just fine.
