The '13 and '14 cars are extremely similar, and I believe all parts will transfer over between the two. The '15 car has the same suspension parts (basically the front and rear ends are the same), but the center/chassis is all different to accommodate the shorty pack, center diff, etc.

From what I can remember the 14 car had some parts like diff cases beefed up and the arms are narrower where the hinge pin goes thru so you can adjust the wheelbase. But they mostly share the same parts.

I just went through the "contact us" link on the A-Main website...
http://www.amain.com/contactus

Below is the response I received:
"Thank you for your email. As soon as we get the parts in stock we will be contacting everyone who we sold XB4's to offer them replacement parts.
We will contact you as soon as we get them in stock. Thank you!"

Arms, bulkheads, steering ,hubs, shocks, outdrives all work.

The chassis, center shafts and top plates are different. Plus a few minor changes like metal gears.

Looks like the '16 could be even better!
Thank you for the explanation!

I should have my '15 built for next week. If you're at the track I'll let you take a look at it so you can compare the parts to your kit.

Default XB4 handling problems...

Hey guys,

I am currently driving a XB4 2013.... i race on carpet and when i hit full throttle the car is very difficult to keep in a straight line...its like the rear goes down too much....

Shocks...

Front 37.5
Rear 27.5

What would you guys recomend to fix this issue...

my thought is to put harder shock oils in the rear?

Put some more internal limiters. In your shock. Def go with some thicker oils. Lay your shocks down.

Check out the set ups on petitrc for good advice as well. But just from your description, ya, your oils are way too light, try the 2 hole 1.4 pistons with AE55 up front and tHree hole 1.3 pistons and AE35 in the rear. Use 4 dot springs (or AE or Kyosho equivalent to 4.2 to 4.8lbs) in the front and 2 or 3 dot springs in the back (3.5lbs). 2mm limiters in the shocks front and rear.

Could try a little more anti-sqaut angle in the rear also.

+1. My first change would be more anti-squat. 2nd change would be a stiffer spring, the 3 dot. When you go up in spring you must also go uo in oil weight.
