Chapter 5a - Driving Techniques, Inputs - Steering
The previous chapter and the next couple will really be the meat & potatoes as far as getting faster in autox, with this chapter being one of the most important topics. This chapter will go over driver inputs for steering and throttle & braking. I should note that while I break these up into their own categories, they are all very closely related when we are talking about maximum useable grip of tires, and in general this is also related to the racing line.

I assume by now we all know the classic illustration of the taut string that is tied from the gas pedal to the steering wheel. Basically it means you can't turn and use 100% of the grip and then also throttle and try to exceed 100% of the grip, it's give & take between all the inputs. That much is obvious but I'll cover these topics assuming no one knows anything.
Steering
Steering was a struggle for me early on in 2014. I was very abrupt with my steering wheel. I think this was a combination of poor skill, not looking ahead enough, and not following the line. Abrupt steering puts a lot of load on the tires and a lot of the times will attempt to use more grip than the car has. You want to be as smooth as possible with the steering wheel - quick, but smooth. There is a paradoxical saying that goes "slow is smooth, smooth is fast." Don't yank at the steering wheel. It doesn't mean you can't be fast with it, but think of it more as being quick and nimble with it. I think this late turn, cranking the wheel is somewhat a product of street driving. We're confined to our lane, get all the way nearly into the turn, then crank the wheel to make the turn, the opposite of what you want to do in racing.

If you are an abrupt steerer like me, it is going to take some seat time to get rid of that. If you're not sure whether you are or not, video reviews will really help. I don't know that I would have ever really known without watching the videos. Here's one from my very first event in '14 and one from my last event in the Mini:
Note how, especially after 28s, going through the chicane there I'm really yanking at the wheel, turning late and then whipping the steering wheel to make the turn. I lose grip from trying to turn to fast, and then I understeer and try to turn the wheel even more to complete the turn.
In this video, I'm much smoother with the wheel overall. Things are less frantic because I'm planning ahead more. Still not perfect, I cock the wheel once pretty good at the turn-around at 20s. I make a tight one around 45s too, but that was more because I had to, it was a super tight slalom coming out of a fast sweeper.
Anyway, the point is to be smooth with the steering. Begin the turn earlier than you think you need to and that will help with a lot of it. Also keep in mind that you need less steering inputthan you think you do. There is a saying that goes something along the lines of, whoever has the steering wheel straight for the longest wins the race (all else held equal). What will help you here is to visualize the line you want to take, and only steer enough to follow that line.
I think one of my problems when I started was that as soon as I entered the turn, I wanted to "complete" it right away - I didn't follow a line or make any arcs, I made 90 degree or more acute turns. As soon as I got in the turn, I wanted out. Instead of that, try to ride the racing line with your steering. Finally, be sure to unwind the wheel as you exit. Don't continue turning any more than you have to. I still have a problem with this. Sometimes you get caught up in making swoopy S lines through corners when really you just need to blast through it with minimal steering input.
