Well I ordered the kit tonight. One more question. Since this will be my first 1/10 four wheel buggy...(I'm used to pro4 and 1/8 scale) and I'm going to run the gear center diff. I've noticed that alot of people run 50,000 - 100,000 center diff oil with the xray and other brands. This seems high to me. What would be a good starting point. Thanks again.
I wouldnt go much lower than 100k, 60k feels too light
Calc. Will tell you how much of each to blend.
Oh! JMC I got my center gear diff issue with the button heads rubbing. I carefully tightened down the spur gear crews and also put a .1mm shim on the bearing collar between the rear bearing and diff. Worked out perfa. Also put a dab of dry gear over the button head just to to help with any possible friction/heat. It's crazy how close the Spurs gears button head screws are to the inner motor mont button head.

Awesome. Thanks for the help.
Do the ECS's fit on the xb4'15? Or are they just for the '16? When I look them up on Amain it specifically says compatible with the '16. Part numbers I am looking at are 365200 and 365300.
Also wondering if the rears really make much difference or if the fronts make the most difference

I just picked up an XB4 2015. Im excited to run it this weekend. I tore it down today and tomorrow I hope to starting cleaning and rebuilding it from the ground up. Any suggestions for replacement parts I should have on hand or upgrade I should purchase. Most of time this car will be run on a low to medium bite dirt track.
Thanks

do upstop shims go above the spring cups or below?

From what I've researched the drive shaft lengths are the same on the 14, 15 & 16 XB4's with the hubs/spindles being the same also. Spec-R came out with their ECS shafts back when the 14 was the latest XB4 available so in theory they should work fine.
ECS will work fine on your 14. Before assembling them fully clean the grubs screws, barells, pins etc. I would not grease/lubricate before or during assembly, thus waiting a full night for the Loctite to fully cure. I would also use the gel version loctite (blue) as it adheres much better.
Fellas quick question..........I wasn't aware that you can remove the upper decks on a 15'. I thought we had to run the car that way. I saw a pic today of a 15 without top decks........ Can someone who's done this post the part#'s needed
If you run in shorty configuration, you will need part #361168.
If you run in saddle pack configuration, you will need part #361169
Check them out because they make the car feel better in every way.
In addition to what Freeski said I also run the front brace. Part#361173
