Some time has passed since last time I wrote it, so worth reminding that this car is awesome!
I am now using big bores at the rear end (TLR, with AE cups): they weight 15g more but work better.
I also installed the gear diff, which is another 10g more.
The package behaves very well!!
I am thinking of playing a bit with the ballast, maybe removing some grams from the 87g "brick"...
