little trick i found to make the front end of your xmod much tighter giving it superb control, i havnt seen anything like this posted here yet.
put a small washer on top of your front arms then fasten it.
simple huh?
cool find i'll have to try it later...i've also used shrink wrap around the tie rod,servo horn, and the bottom of the steering knuckles...the servo doens't seem as responsive and it sometimes get stuck
GPM front suspension arms do the same thing, although with little white plastic washers (at least later revisions...the first ones to come out didn't ) It does make the suspension more stable and prevents the screw from sometimes catching the hole.
