Come to think about it I had the same issue with missing that spacer too.
My son had his first drive in the FX (and a first drive for any F1) last Friday. Lots of f1 learning to do.
Loosened the diff to be just right stopped the car from hooking on power, set some negative steering and throttle curve made the car drivable.
One of the other drivers suggested thicker lube in the side tubes. We will try 100k instead of 20k.
I would not recommend the Serpent Sf2 front wing as it lasted for one race only. Another car and ours had the same issue.
