Has anyone ever tried boiling the front a arms to make them more pliable by chance? I hear this can reduce the likelihood of breakage on minor impacts.

Those are the standard Rustler, Bandit, Slash, etc hexs. Tra1654, $2 and they come with extra cross pins. You'll just need to put a clutch shim behind the pin to take a little slop out. They're also nice because they snap onto the pin so they won't fall off every time you take your wheels off.

Hinge pin holders 1 mm offset with hinge pins on the lowest setting RF RR.

Drives like my ebuggy, rear stuck on power with a bit of push, tonnes of steering off power.
Alok, tried something very close to your setup today at delta and the car was way better. The track was bone dry and very slippery. Started out with the Vik setup from Reedy and car was pretty much undriveable. Tried your setup with a couple changes and car was dialed. Very driveable and a lot of forward bite. Was actually able to move the rear hubs back and still had plenty of bite. Ended up with 5k/2k diff fluids, 1.4/1.0 sway bars, and rear camber link out on hub. Also didn't have the 3 dot front springs so I ran losi black 4.1 rate.

Just picked up a new 2014 XB4 to replace my 2013 v2. I wanted to give everyone a heads up on a wear and tear part to keep an eye on. As I was cleaning up my 2013 XB4 for sale, I happened to notice the front center drive shaft had a ton of forward and back play. When I took off the plastic retaining collar where the shaft connect to the universal joint, I noticed the holes in the universal joint were horribly egged out by the pin. I raced this car every weekend since late October on a high bite clay track. I took the front center universal joint apart once in December because I noticed the pin began to walk and tried to protrude through the plastic retainer collar. The pin was slightly worn and I probably should have replaced it but I didn't have any on hand so I put it back together. I don't recall any issues with the universal joint at the time. Two months later that pin has about 50% of the diameter left and the holes in the universal shaft are eaten almost all the way through. DAYAM! The rear center universal shaft is as tight as a drum, retained most of the grease and never once has the pin tried to walk on that end. So keep an eye on your front center universal joint, keep it lubed and replace the pin each time you lube it!

1 mm narrow compared to 2013 specs or the 2014 wheels? The 2014 wheels
are 1mm narrower than the 2013.

Very cool, theres some other roll center stuff we can compare on both cars saturday (the hinge pin inserts/tower mounting locations as well). Also the new slipper pad/spring rocks! Never tried that low a diff oil on the rear might give it a whack this time!

What do you keep these lubed with.....and do you pack it or just a thin film??

I'll be joining the XB4 family here soon. Purchased the 2014, should be here by end of the week. I've been reading up on here and on Petitrc. If you guys have any tricks, things to watch for during my build please let me know.
Thanks!
