Hard to tell from the video, but your car looks to be pushing going into the corner. Is that the case?

If I were you and we're looking for more steering the first thing I'd do is shorten the rear camber link if you haven't done that already. If that's not enough I'd narrow the front track width moving the dot inward. and move the hinge pins to the bottom position. The +1 inside bottom corner for max front end grip. If that's not enough move the rear hinge pin up, this will keep the rear flatter and give you more steering also...

What is the internal drive ratio of the 2014 XB4? I am trying to figure out FDR.
Also how do I determine what the FDR should be for different turn motors? My 17.5 Trinity came with a manual that says for 1/10 buggy to be between 5.5-6.5 but I also have a 8.5T and 6.5T tekin and LRP and not sure what the FDR should be for those.

On the Xray site you will find all the specifications for each model under "Specs".

For the XB4 you can find it here (specs for gearing have been the same since 2013):

So 1:2.5... does that mean when I calculate the FDR I do (spur/pinion) x2.5=FDR?

Yes, we had a little discussion about the car and 13.5 motors a short while back. http://www.rctech.net/forum/14262709-post9310.html

Fellas quick question.......im new to xb4. I purchased a 15' n wanted to know if it's possible to use a few of the updated parts from the16' mostly interested in the stronger front diff case n front arms! If its possible will i need to also use the 16' front tower?? Thanks

Yes the cases will work but yes you will either need to get a '16 front shock tower or do some dremeling to the '15 tower.

Also, the '16 tower geometry is a little different.

Spork

I recently completed the build on a 2016, and plan to run 13.5. However, with the stock spur, the largest pinion I can fit is a 26. I'd like to try a 29. Any idea what I might be doing wrong, or did wrong in the build?

Thanks

Xray sells smaller spur gears that should help you out...
