Yes I gave in .
Even with weeks upon weeks and a lot of X-ray driver advice it would not stop diffing out
Tried almost everything including . New towers . Shocks . Many a diff oil change .
Bought a second hand yz-2 ca - setup with same diff oil same suspension oil.
Did my fastest laps straight away
Now I not a xray hater I have both xb4 and t4 both 18 specs and these are brilliant and not going anywhere soon .
Thanks for the help guys btw .
