Question regarding the ball differential: is this using 1/8 diff balls? I tried to look at some replacement parts, and only see full diff sets and the diff gear so I couldn't tell. I counted the openings in the diff gear and see 12, so it leads me to believe they're 1/8 balls - which I think is a great thing. I love how the diffs build and last on my SRX2 which also uses 1/8 balls.

XB4 stock part #930220 which are 2.4mm ceramic balls.
XB2 stock part #930120 which are 2.4mm carbide balls.
We recommended gluing the diff rings to the outdrives and change to carbide diff balls for the XB4 ball diff due to soft rings.
This will give much better performance and significantly greater life span.
For the XB2 diff it's only necessary to open it and ensure they have enough grease added and then do a proper run in.
XB2 Dirt Edition will come with it's own instructions on how to break in and setup the diff and slipper clutch

He is right... Theoretically.
But sometimes theory doesn't play out in the real world.
I can't really explain this to someone without drawing a picture.
Regardless, it would seem that most are finding more grip with the shocks in back. It's just counter intuitive to everything we know about weight transfer. Maybe a long wheel base would help this car too, in low grip, as it seems slowing rotation is a greater benefit than adding weight transfer to rear.

In any event this will be my next buggy as I saw these on our track yesterday and they looked super dialed.

New XB2 Lexan™ Rear Wing 1.5mm
• Thicker 1.5mm Lexan™ material
• Increased reliability
• Increased traction & stability
• Increased lifespan
Optional REAR wing for XB2 made from thick 1.5mm Lexan™ material is highly reliable with less chance of breakage, gives higher traction & stability, but reduces steering.

I pre-apologize if this is a question that has been asked before, I don't have a lot of time at the moment to read through this entire thread (although I will soon). I'm seriously considering pre-ordering the dirt XB2 (about 90% there, was about to get a Schumacher KF2 but I reconsidered when I saw this car) and would like to pick up some basic replacement parts since I don't have any X-Ray stuff whatsoever. I'm primarily an on-road guy, and just wanting to play with off-road occasionally, so I'm not looking to go super insane with every hop-up, I just want to avoid ending a race-day early if I break something basic. Or if people have experienced issues with a part included with the car, I'd rather avoid issues and just buy the better part right off the bat.
Anyone have a list of recommended parts when starting off with this platform brand new? I will be running primarily 17.5 on a relatively large outdoor hard packed dirt track.
Edit: One specific question I have at the moment is what alloy servo arm works the best for this car? I assume it comes with a plastic horn, or none at all. Also, is there a preferred servo that easily drops into this car? I was considering a shorty to gain some space for the electronics. The last time I drove an off-road buggy was the RC10 when chassis space was plentiful and pretty much anything fit.

as far as the horn, mine came with 3 plastic horns, i think it was 23 to 25 tooth.
for the electronics, i had a bit of a hard time fitting my r10. i eventually was able to get it fit nicely, but i had some issues because i wanted to route my wires nicely.
i cant say enough about this truck. it is really terrific

What I really like about the Xray cars is that they are 100% competitive out of the box. I don't think you need any upgrades at all. As far as servos go I'm pretty snobby but I really like the Savox 2263 brushless shorty. I've sold a billion of them at the track. They are fast, durable, and smooth. Nothing like the garbage disposal sounding 1257 & 1258s.
