I did some small changes on the setup (previous setup).
Changed to a bit less Ackerman.
Put the 1.0mm steering spacer back in and reduced the front toe angle from +0.75deg to +0.5deg.
The car is easier and more constant to drive through corners.
Turn radius is now really close together between full on the limit and taking speed out a bit.
Also put the 5g weight in front of servo (position B) and also 10g between ESC and motor.
Car is now perfect in balance and exact at 1320g weight with a bit lighter body.

Drove it on friday when the track is quiet cold, as they just turn on the heater when they open on friday for the weekend.
So the friday times are always slower then on Saturday or Sunday.
But I could manage to drive constant low 10.6 times and fastest 10.553sec.
That is around 0.1-0.15 sec faster than my times on Fridays before with the other setup.
