About time somebody makes 12 degree castor blocks for a fair price!
About time somebody makes 12 degree castor blocks for a fair price!
They may have been out for touring cars for awhile but I'm thinking perhaps they take more strain on a car that can be landing consistently from a few feet in the air. I applied lock-tite to the screw/barrel before greasing it and placing it in the shaft. Luckily as mine came out I was able to find the shaft so as to not be out $45. I'm still trying to locate the correct parts to replace the barrel, pin and set screw as most part numbers point to the T2 touring car and am not sure if they are compatible.
On the track I have to say I did instantly notice a positive difference. The car was able to enter and exit corners much faster and landed jumps on power astonishingly well. It was like a new car to me. Although this was quickly crushed by losing parts and the shaft causing a DNF for the round.

Almost finished putting my 16 kit together and to be honest it's my first kit I have ever put together. I'm cheap and have always bought used. All I can say is this kit has went together perfectly and the fit and finish goes above and beyond any of my expectations. Can some one recommend a good pininion and servo arm I'm running a 6.5 on a smaller tight indoor track with gear diff with stock spur thanks .

I had the same problem and this might sound crazy but try +5mm of bump steer washers and the rear ackerman position on the steering rack. This made the car have alot more steering. Setup sheet I got this from: http://site.petitrc.com/setup/xray/s...irt2015080309/
ECS Front Shafts??
I broke a front drive shaft tonight on my 14 XB4 and was curious if the new ECS front shafts would work with my 2014 model. If not what specifically is the issue/difference as the regular shafts are 81mm on the 14, 15 & 16 XB4's? I guess the spec R's might be an option as well, but thought I'd ask before making a costly mistake.
Thanks,

Try this:
- Go in in Center diff oil. try 200/300K
- Go up in Rear diff oil. I usally run 8K but you can match the front @ 6K
- Put a sway bar on the rear only
- lengthen the wheelbase by moving the rear hubs back
- run the back holes on the ackerman plate.
if that doesn't work I have a few other things you can try.

I went ahead and ordered them(preordered - out of stock everywhere) as I remember the SpecR ECS shafts have been around for a few years and are basically the same thing. I've been having good luck with the 14 and plan on holding off on a new kit while the current one works well on my tracks low-bite, hard-pack dirt. Really hope the Xray ECS shafts are more durable than the SpecR units that are half the cost....

Hello everyone. Thinking of getting a 2016 xb4. I will be running an indoor medium grip track. Would the center gear diff be a smart upgrade? Are there any other must have parts? Also can you use 12mm hexs on this car? Since I have some wheels from another car. Thanks for any and all help.
