Pretty! How much are those? And they must weigh about a pound.

At a certain point, it's going to be more cost effective to just bolt some axles onto a bar of brass...

I'm not loving the steering arm bolted to the housing and the single shear design.

I'm sticking with the the logic of lighter is better to a certain extent... I'll move necessary weight as low and strategic as possible.... I can see adding a few oz/g to each corner. But how much un sprung weight do you really want to add to a trail truck? These aren't comp crawlers. Just an easy way to sell a bunch of shiney things it seems. Besides, I prefer my brass American and loaded in magazines...

The addition of weight down low on the TRX4 is directly connected to weather you intend to run the Rover body (top heavy). If you're going to use a lighter body, the addition of the extra weight is not needed.
Also, if this is a trail truck used for dirt trails and mild climbs, run it stock. I like to climb rocks and the lower the CG, the better the truck handles the steeper angles before it flips or looses traction.

I agree entirely... I use mine strictly as a crawler, so I never even ran it with the LR body. If I were to use it with the original body, for me it'd be a trail truck. Then I wouldn't want the added weight.

In my opinion, adding low weight to TRX4 is not only a good idea but a requirement to be somewhat competitive as a rock crawler. Sorry, someone may disagree but I am one of the people here who believes TRX has a potential to be a decent crawler. While experimenting, upgrading and running with a group of experienced rock crawlers, I found that moving available weight down low has its limits. Changing body, getting metal bumpers, lowering suspension and relocating battery and electronics to custom pans helped, for sure, but the truck would still flip over before the tires loose their traction. I believe that brass inner/outer portal covers and c-hubs are the best option since they are down low, non-rotating, and comp legal(correct me if I'm wrong).
Having said that, I also agree with the extra weight is not always good. I had trouble keeping up with lighter trucks on sand or loose stuff. Finding good balance might be the key here.

Please let us know how that inner brass housings perform and hold up.

The "brass craze" makes perfect sense. It's denser than steel, so you can lower the CoG more with parts that are the same size as stock (less need for big chunky weights). You can powdercoat it if you can't stand the appearance of natural brass.
