I attended an autox school this weekend organized by the local sports car club which really helped me pinpoint what I was doing wrong.
My instructors said I was basically too jerky with my steering wheel input, which would unsettle the car on the course. They basically said i needed a dampener like they have on motorocycles to slow me down.
Would you guys have any tips, or tricks that would help stop this problem???
TIA

 

Look ahead more. Seriously.

The farther ahead you look, the smoother you'll be.

That, and lay off the double expresso.

 

Looking ahead is the key. When you look ahead you know what's coming up sooner so you have longer to make your input which means the input can be smoother. Also by looking ahead you make fewer unnecessary corrections for the next gate and instead make the corrections that you will need 3 gates ahead.

Basically the idea of looking ahead is to make everything slow down in your head. How do you think F1 driver's do the same thing at 200 mph?

Here's a good visualization. Pretend there's a string that goes around the sterring column and is hooked up to your feet. As you turn the wheel the string tightens and your feet cannot press the pedals all the way down. As you unwind the wheel you can feed in more power. But you can't feed in full power when the wheel is turned sharp.

 

The basic rule is that you should only have 1 steering input per turn (less if possible). It's hard to catch yourself doing it but an in-car camera will show exactly how many times you turn the steering wheel.

That's part of what people talk about when they say be "smooth". I see a lot of drivers turn in, unwind, turn in again, unwind, turn in more, unwind, etc... which is not smooth at all.

Also, when being jerky you will reduce the traction of the front tires. I think of it like walking on a waxed floor with socks on. If you move smoothly it's no problem but if you try to sprint you go nowhere.
