Haven't tweaked it to perfection yet but still feels pretty good. Careful in corners after long straights - the front tyres cool quite quickly on this car.
Monza Junior setup, credit to Christian Haba, this is his above setup with adjustments for the Junior layout (adjusted gears, camber and tyre pressures).
Setup with different, closer together gears. Not sure which I prefer. This setup basically means only one downchange through the whole lap (that in the first corner).
