Interesting discussion to follow about tuning. After 50 years of racing, on and off road, on 2 and 4 wheels, I have seen that when it comes to faster lap times you have to do your changes and adjustments in the following order: 1 Driver 2 Driver 3 Driver 4 Rubber 5 Brakes and chassie 6 Engine
The other way around just cost a lot of money and breakdowns - Drive and have fun. Looking forward to track meets on three wheels
