Tie Rod/Camber solution
 

Maybe it has been posted before, but here's my solution for the tie rod/camber problem.

Since the plastic of the rod is to soft, I searched for something to slip over the rods. This is what I found :

Fisher brass fixings MS 6x22 (art-nr. 90520 - 15 pieces for 5.50€)

Thread the rods, cut down the fixings and turn them on the rod. The turnbuckles are really thight now. The consequence is that you can no longer turn the turnbuckles without the rods popping from the ball. But I prefer this over my camber being off with every hit I take.

Like the way you are thinking. I use the Losi white HD cups and they are fine but also TD did release a new version of the ball cups which are a much tighter fit that also cures the problem.

The later camber links/ball studs are fine. No need for this mod buddy.
