The car is arguably the best 13.5t car due to its light weight and light drivetrain, with that said to me after running only 6.5t motors a 13.5t would feels slow...

I think it depends on the track. Mine have 13.5s and I've won occasionally with both on my home track which has few long straights. None actually. I recently went to another track where more than half of the track was wide open straight and I could not keep up....but I still did ok. 13.5 is great because the drive train lasts forever and its a lot harder to overdrive the car which I find most people doing. I, myself, am pretty slow but extremely consistent.

I feel the xray has more drive train drag than many other 4wd's on the market....

this was after I cleaned and re-lubed bearings.

which seems a shame, as their onroad cars roll on forever!

this is the 13 model though, wouldn't think the 16 model will be much freer

The XB4 has by far the least drive train drag of any 4WD on the market.

So if your '13 doesn't it's in serious need of a rebuild

Looking at buying a new 4wd buggy I have been with kyosho for years and am ready to switch it up and the 2016 xb4 looks verry speaking .
My dilema is I race on a smaller indoor medeum traction track and from what I have seen and read this car is more suited for med high and high traction tracks . can any one tell me if this car is doing well on low med tracks also when I order the kit is there any thing else I shuld get such as some different springs or shock pistons right off the bat thanks all

I do the same for shock orings but only soak them for 10 minutes.
We never build the diffs with grease as this will keep the o-rings from swelling and sealing properly.

As Norse says, let the o-rings soak in shock oil before assembly, don't dry them off and use grease only on the outdrives when assembling.

This will ensure leak free diffs

XB4 is just as amazing on low to medium traction clay or dirt with the optional medium chassis braces (#361294 + #361295) and medium chassis side guards (#361265).

The stock hard chassis braces and side guards give less traction and makes it feel twitchy on low to medium grip.

Other than these parts we prefer to run the optional 1 dot front and rear springs on low to medium grip and drill the stock shock pistons to 2x1.6 front and 2x1.7 rear or you could buy the 4-hole Avid or Schelle etc. 2x1.5+2x1.1 front and 2x1.6+2x1.1 rear pistons.

Quote:
New XB4 Composite Chassis Braces
• Fine chassis flex adjustment
• Medium hardness composite material
• Increase traction
• For medium and low-traction tracks
Optional medium-hardness front and rear chassis braces, softer than the brace included in the kit, used for fine chassis flex adjustment. These medium-hardness braces make the chassis more flexible, and are recommended for medium and low–traction tracks.
#361294 Composite Chassis Brace Front - Medium
#361295 Composite Chassis Brace Rear – Medium

If running the center diff on low traction tight tracks we usually run it with 500.000cst grease and 5/3 or 3/2 in the front/rear diffs.

For medium traction we usually run 1.000.000cst grease in the center and higher front/rear diff oils such as 8/8 and 10/8.

Center diff is not included though.

I am probably going to get rid of my '14 and pick up a '16 simply to be able to run short batteries and have the updated towers and main chassis. (or I might get a Team C TM4.shhhhhhh)
