No traction control needed.
Beautifully balanced tune, fairly quick for 600pp but the secret is to keep the car on boost. The best way to do it is to make the gearbox more aggressive so that it gets to 6th much earlier, then you use the final gear to max out at 300km/h+. You will need to up the maximum speed from 180km/h to 190km/h to achieve this.
If you are not on boost and getting out of the corners slower, then the opposition will get away from you.
Changed the gearbox for Tokyo 246 and immediately found 2.5 seconds per lap. Haven't tried Mt Panorama yet, but it will be pretty quick, particularly over the top of the mountain as it has so much grip.
Going to try it without ballast, wish me luck.
Great tune GR 65, best as always.
