hey.. orlando... I don't have the ball cup pooping problem in my car (RDX and BD)..
Maybe because i replace them every once in a while
they do bent out of the shape from me hitting the corner too many time at the same spot!....
Losi white ball cup / tamiya ball cup / HPI ball cup are pretty good also, as they are a bit stiffer then the standard yok cup!
Just wonder guys... what spacer shim are you using to adjust the roll center from the chassis post? Trying to make the camber link shorter for carpet racing.
