A couple of laps from carpet practice today with the Xb4 '16.

CRC carpet and Clik-Track barriers

Track opened a couple of days ago and is still under construction.
More elements will be added but finally we have a place to practice close by in the winter time

+ YouTube Video

Thank you Bent. I was planning on buying a yz-4 and may still do so but after building the new 16 I was so impressed by the quality and fit and finish that I'm gonna buy one... I got to turn some laps with it too and it was quite good but needed a little work(first pack on the car was as fast as my bmax4 III), the car had too much turn in and too much on power mid corner push (box setul).... any suggestions or should I just try the Martin Bayer/Malin clay setup?

12 degree castor blocks with help out a lot also raise the front link and try a shorty servo and 15k in front diff. I always play around with steering epa also as a quick fix. Get the xb4! It's such a precise car that is super easy to work on, it's been my favorite wheeler for the past few years.

What rear center stiffener did you remove. I didnt know they had anything that could be removed besides the screws on the bottom of the chassis for flex. a part number would be great. thanks for the help

You can remove the rear top deck for more traction.

Just switched to center on my xb4 2015, the car just feels so much better for me.

Hi bentka do you have setup for low to medium dirt with pretty big jumps (for a 1/10th).

Right now i'm using 5 - 100k - 3

the car felt really good most of the day but as it got dustier it became a bit loose in the rear and a bit twitchy. Still drivable though.

Thanks, I'm already running the front link in the upper hole in the tower... I was hoping I would need to buy the 12° caster blocks... I'm gonna try Martin/Malins clay setup, i just need some springs and a swaybar...if that doesn't give me what I'm looking for I'll buy the 12° caster blocks. ..

Yeah I know it seriously sucks having to spend $90 for the blocks but they do help a lot. I did contact spec r about making some 12 degree blocks and he seemed interested so we shall see if he decides to produce them. Sway bars go a long ways also. I'm on high bite carpet running the yatabe setup and the car is absolutely fantastic.

I have an XB4 coming my way, can someone recommend a good starting setup for medium to high bite clay tracks? Specifically for OCRC, LRH and other local California tracks.

Does anyone know how much wider the new style bodies are compared to the 2014 version? I cannot find a body for my 2014 anywhere.
Also wondering what the actual part number would be for the older style.

  • '16 body #369703 : rear section = 119mm wide / widest front part = 126mm
  • '15 body #369702 : rear section = 116mm wide / widest front part = 124mm
  • 13 / '14 body #369700 : rear section = 109mm wide / widest front part = 122mm

All measurements done on new uncut bodies.

I would give the stock setup a try first. It actaully seems pretty good.

The only things I would do off the bat is get some of the Schelle pistons. 1.6x2 front and 1.1/1.5 x 4 rear. play with the oils a bit.
