Need some carpet tire advice.
1. If running the Schumacher mini pin rears what compound works? Can I run the hard compound to prolong life or should I be running the yellow softs?
2. For the cut stagger wide (4wd) front tires they don't sell pre mounted it looks like and the they don't come with foams. I don't run foam in my 2wd so should I not run it in the 4wd either?
3. What front wheels do I need to mount those? It looks like the bead is different than most.
4. The schumachers worked better than the proline pin points/wedges in My 2wd. Assuming they will be better on the 4wd too? Or do most ppl run the prolines for 4wd?

I run on medium to high bite clay and have been running 300K. Ive tried the 500k, but lap times showed to be slower but easier to drive. When I went back to the 300k, I could turn faster laps times and IMO still easy to drive.

Has anyone tried the B64D body on an XB4? I bought the finisher body for the XB4 and I'm not liking the look as much as the body that comes with the B64D. I read in the B64D thread someone was able to use an XB4 body on the B64D but would like to hear if the reverse works as well.

Disconnect servo linkage and see if you manually move steering to left and right without binding. If you can, there must be something wrong with your servo (have seen that before) or transmitter L/R throw.

I am also wondering... do all the xb4'17 hard parts fit the '16? Or are there some parts that won't work on the '16?

16 and 17 are the same car... All parts are interchangeable.

My `17 is perfect. I believe you have setup L/R throw in your transmitter correct?

Also same thing when they tried my XB4 body, with more trimming it would fit.

This might come off as a dumb question but, is there a way to adjust the servo mount? Using a protek 160T and the servo horns don't line up with servo mount. I was hoping to using the protek servo washers but ended up using the rubber bushings instead. Thanks in advance.

Anyone running the wide stagger front Schumacher tires.... do you run foams in those front tires? And will they work with standard X-ray 12mm hex wheels? I looked at some X-ray setups but I couldn't find the answer to these specific questions .
Was also wondering how the 12deg caster blocks are compared to the 9deg. Was thinking about getting the alum 12deg

Just got a XB4 '16 and ran it for the first time on hard packed dirt (dusty). Moved the steering to the front hole on the arm as per previous pages to reduce the steering sensitivity. The car was really good to drive, but over jumps the nose seems to dive really easily, and I have to stay on 50-75% throttle so it lands properly.
Shocks are standard setting, 35wt front, 30wt rear. ride height 20mm. 7k, slipper, 5k.
Should I shift weight rearwards (motor is in forward pos), or is it something else?

Jconcepts or proline open cell foams work good for this, the schumacher ones are a bit narrow to cut in half.
The tires mount a specific way. If you look at the tread there are 2 row separated by a mold line and 3 more
rows of tread.You want the 2 rows facing out. If you run the 3 rows out they have to much steering.
Schumacher tires always fit best on there rims due to the width of the glue
bead but you can usually get them on other rims. Make sure not to glue the
flex section of the sidewall down.
