Hope this helps ?!!

Im keen on getting the Aluminium ( GKA or HR don't care) rear chassis brace.
I've broke 1 plastic one and bent the crap out of another which bent my rear dog bone.
What do you boys think will it just put more pressure and bust the diff case / bulkhead ??? I want to be able to launch as heigh as I want limiting the damage. The brace must have been fully tested on the Kraton how did it go ??

@Camo my Kraton brace has worked well, but I've tweaked rear suspension mount and cracked the rear diff case, too doing huge airs. Like anything, these rigs have limits on how much abuse they'll take. Even with good landings, if shocks don't break, the hinge pins at suspension mounts/A arms and in rear hubs will bow/tweak. You likely won't notice until you go to remove them after huge flat ground landings. After awhile they can start binding badly and become difficult to remove.

@Rich Duperbash Your right !! I think I just like fixing her lol !! It's hard not to get obsessed with making them bulletproof bra. Have you seen the Aluminium diff cases GKA are working on ??

@Camo yes, very easy to obsess with mods/upgrades. I'll likely try the diff case in the rear if mine keep breaking. Was going to try longer screws from suspension mount into flutes first. Think slightly tweaked mount plate and horrible rear wheel landing did the damage. May try fabbing a rear mount support that secures to the chassis, similar to how front rear suspension mount attaches. Too much aluminum adds weight pretty quickly, though. Love wrenching, just get frustrated with repeat failures. Running HR rear Kraton support now with tower to tower, starting to wonder if setup is too rigid?

@Rich Duperbash this is my fear.
I keep toggling on whether to do the tower to tower brace.
I have GKA front and rear chassis braces and I fear by adding the TTT brace it might make the entire thing too stiff?
I was thinking about using a plastic tube instead of aluminum.
This would definitely provide some added rigidity, but allow for some flex as well...

@Buck it's totally up to you whether you feel you need it. If you don't plan on doing big 10 ft plus jumps, you may not need one. The GKA chassis supports may be enough. You might consider just adding a rubber grommet to either end of a tower brace to provide slight give. That has worked well for my Outcast brace. I like to think that all of these parts are repairable or replaceable either way should something fail or not work out. Takes some of the worry away cuz breakages are simply part of this hobby.

@Buck you could try using a carbon arrow shaft ?
Might give you a bit of flex. The Aluminium I used had a fair bit of flex in the longer length I bought but when you cut it short to fit the car it's pretty stiff. I think if you go hard enough something will bend or brake. Gotta keep pushing the boundaries !!! Go hard
