XRAY - Model racing cars

Hi, i'm italian and my name is Stefano, and i have this problem:
Today, by adjusting the rear camber by increasing the inclination inwards, I noticed that the smoothness from bottom to top and back, arm and lower back brake ....
if you shrink the camnbre, smoothness rotorna excellent (bars with shock absorbers and detached).
Who can tell me if it is normal or is there anything wrong?

PS my model is new again, out of the box and is a 2012 T3
Thank you for any replies

how much camber have you set

With the gear diff and the 52mm driveshafts this is normal if you go over 2 degrees camber (in some cases maybe a bit more).
A solution if you want to run more than 2 degrees camber is to grind down the plastic piece that goes on the driveshaft so that it does not bind in the gear diff's outdrives.

I you want 3 degrees camber then grind down the plastic bit that goes on the driveshaft.
