Asc,
I just starting practicing with mine last week. All stock, except pistons/oil, no upgrade parts yet. I run an indoor clay track with a 6.5 Reedy Sonic. Much fun! I have had my share of nose dives, slapping landings getting used to the car, but no breaks. Checked my diffs and no leaks, no cracks anywhere yet. Amain says my upgrade kit shipped today, but I will run it as is until something gives.
What kind of track and car setup are you using? My first day, I ran the complete stock clay setup. Having come from a B44.2, which I really do like, I sort of copied my shock setup and drilled out two hole pistons to 1.6 for the front and 1.7 for the rear. 35 wt front 30 wt rear. It is really quick, turns great, excellent punch. Maybe just a little loose in the rear if i really hit the throttle coming out of the corner, so I may add a little ballast or lighten the rear diff oil. Not sure yet. Too soon to say.
Any setup tips you may have would be appreciated.
Just a great car!

I run the stock class in Aus as well and I use AE 69 Spur with 31t pinion and no timing (temp around 60c).

Here's a race at the LHS last night...several Xrays making their way into the local scene. I don't do the car any justice...I run the pink one...finished 7th (the others finished higher)

Secretary from work just called to say the brown van dropped off a package with my name on it. I wonder what it could be... 
Can't wait to dig into this thing tonight!

Gotta hand it to XRay. Seemed to have merged all the durability offerings of gear diffs and beefy suspension components and arms (which is why I want to get rid of my B44.2) and has a more chassis friendly layouts for electonics (which is why I dumped the DEX410).
Along they way they added some really great tuning features.
A+, XRay.

I got my kit last week, my fix-it order showed up this PM. Pretty nice. Mostly ambivalent about aluminum braces for a carbon shock tower. Not true; I'm mostly disappointed actually, considering the premium cost for parts. I know aluminum vs. CF in a high center of gravity area is not a design choice that Xray wanted to make - but I understand economics. I'll be fabbing up or buying some more beefy carbon bling to keep things in the spirit of what Xray stands for. It's nothing that'll lose you a race, I just wish Xray came out of the gate with more study CF towers if that's what was needed.

I was thrashing the heck out of the car the other night and it was bulletproof.

A helpful tech tip for those with the XB4, don't try to use the Xray parts on other cars. I needed to replace the rear hinge pins on my RB6 and all I had was XB4 ones so I cut them to fit. Then this happened, also needs to be said that the hinge pin is still perfect.
Xray stuff is tough!
