One of the first things to realize when it comes to car control and attending your first event is that things need to be linked together. You are not shooting down a straight, going through the braking area and then turning the corner. You need to imagine the entire course as a fluid trip and find the fast way from one element to the next. It is always easier to start out slow and learn to speed up then to develop habits that you need to “unlearn” later. This is not to say the Solo racing is not aggressive because it is, and once you “get it” meaning the flow of it you will ramp up the energy to combine fury with smooth.
A common mistake for beginners is to make the car extremely stiff right off the start. This places far more pressure on you as a novice because the car will react faster than you know how to. In this situation you will always be behind the car (slower) and take much longer to get it right. The softer set up will be slower than a properly driven set up car, but a poorly driven stiff car will always be slower than a well driven soft car. The tires will not have as much time to communicate with you before loosing traction when a car is stiff, and they will take a “set” faster making the available slip angle (steering angle or sliding angle of the tire) much smaller thus the window of grip will be reduced for you to “learn”.
Check tires often so you can see how the changing temps affect the pressures. This will help you learn how to “tune” the cars handling without having to change parts right away. You will also be able to optimize overall grip of the existing suspension. If you notice something irregular with your vehicle, bring it to an auto repair shop immediately. If you are having problems with the brakes, then you may consider replacing those using an auto front disc brake conversion kit.
Don’t mistake the markings on the sidewalls (scuff marks onto the sidewall of the tire after a run) as always the need to add air. Ask yourself if you caused it or the tire did. Over steering when you have lost grip will cause this and the hardest thing to learn is that you are are causing it and not always the car. You need to get the feel for when you have lost grip and “stop” turning the wheel, this is the way you let the grip catch up. This is one of the absolute hardest things to learn about car control and when you master it you will be amazed what can be done with a car.
