If you're planning to drive a 122 Hps car with 200 kmh, then of course it will be unstable at some point. These cars are to be driven at around 140-160 max. You need at least 150-160 Hps for a fast racing car.
Not sure what you mean with unstable. I have one of these and they feel solid on the road at 200km/h. Make sure you have good tyre's on the car and that they are balanced.
@@wrndlabs Obviously tyres play a role but still 122 ps is not enough for a car to be driven constantly at a speed of 200km/h. It can cause damage to the engine, especially since VW overheat easier.
