Anyone have any shorty servos in their car, if so what fits without modding the wire

I am using X-ray servo mount for the shorty.

Didn't Brent say that changes the geometry using the aluminum mounts?

Coming from an RB6. The XB2 was definitely an impulse buy. My track is a smaller indoor astro turf track with high traction. The RB6 was in my opinion pretty darn good, but I get bored easily. I love my newly built 2016 XB4 so much, that for now, I have decided to part ways with Kyosho. People think I'm taking a step back... but the XB4 is no joke. I'm hoping the carpet edition XB2 is also similar in feel and track manners.
I understand how new the XB2 chassis is, but I will have it in a few days and I'm in need for a good astro setup. The Bruno Coelho worlds setup was great for the 16 XB4. Any good starting points that I am not aware of for the XB2?

Here's some pics from my TLR 22-3.0 build, I'd be very interested to see what the measurements are for each comparable XB2 part so we we're comparing apples to apples:
Stock Ball diff in the kit = 32.5g
Stock Gear diff from XXX series which is forward compatible with the 22 series = 36.2g
MIP Lightened Ball Diff = 17.2g
Stock Slipper pad parts = 12.4g
Exotek Slipper Eliminator Upgrade = 3.8g
Stock CVD's = 24.9g
MIP Puck CVD's = 17.8g
Obviously weight doesn't matter for open mod cars, but anyone who has raced a stock class with stock parts and then switched to lightened parts will see a significant difference in performance with shorter ramp ups to clear jumps allowing tighter lines, faster acceleration and faster top speed.
*** UPDATE
Stock steel screws on slipper eliminator = 1.3g
Upgraded titanium screws = 0.7g

Stock slipper parts.. 13.8g
Stock rear axels. 21.9g
Stock ball diff.. 28.7g
I didn't pull out the gear diff.. Or their screws..

i have been looking at this buggy and i am pretty sure it is going to be my next purchase... One thing i dont understand, what the is the "Luxury" part of the truck that is on the box and in the advertisements?
I get i dont understand the marketing on it...any have an idea what its about

Regarding the mass distribution, for a simple rod like an axle shaft the formula is
A handy List of moments of inertia for various shapes, which is also linked from the page Seth provided. Although to be fair I don't think it changes your conclusions, just occurred to me while reading along.
Something that will matter, for the spur the rotational speed needs to be considered, as it also spins faster than the axle shafts if I'm not mistaken. Which takes more energy to achieve. Another squared factor:
Rotational energy
Although the lighter axle components do have the additional benefit of reducing unsprung suspension mass, which is a good thing too.

Slow down.
I'm still getting use to red to + and black to -..........

All I gotta say about this car is WOW! I previously had the yz 2 and it was no where near as good as the xb2. On our high bite carpet track I was turning lap times almost identical to my xb4 16! Box stock minus I switched to yatabe springs that suit my driving style more, yellow front green rear and malins hudy arena setup. I can't wait to get the front brass kickup and battery weight. At 1475 the front end just felt a tad light but the car was on rails and super consistent, easily the best 2wd buggy I have driven. Xray knocked it outta the park with this car!
