These are a complete waste of time and money - 7% extra engine power, 5% less drag coefficient, etc…??
At a cost of 30 or 40 silver tokens each??
Yea - they are obviously straight out of War Thunder’s system, and fair enough, but they are totally trivial and secondary and RIDICULOUSLY EXPENSIVE because of that.
They need to be made meaningful - perhaps add some armament options for example, or a lot cheaper.
