Oversteer - Which counter-measure?
 

Hi guys,

I believe most of you guys have gone thru the advanced driving technique. I just need to get your advice on some driving technique for

Rear wheel drive cars:

Over steer.
How to counter measure: you will need to counter steer I believe, then what do you do with the acceralator? You rev or you let it go?

Under steer :
How to counter measure: ??

What abt Front Wheel drive cars:

Over steer.

Under steer :


Appreciate your advice.

Cheers

Well I've never taken any advanced driving course or anything, but lot of driving experience...

I can tell you this about oversteer... it's fun.. haha

but okay.. how to correct it... you must counter steer for sure... pointed in the direction you want to go... and depending on the condition of your oversteer.. you may want to push even more... or you may want to ease off...

by adding more gas... you shift weight to the back.. and give the back more grip which gives it traction and stops the back from sliding out.... however... for most of the driving common people do.. i would advise to not full out gas.. as this can also upset the oversteer condition more... it takes experience to feel the different modes...

really to avoid spinning out.. you have to know your car well... and anticipate when its gonna lose control...


understeer... you have to slow down.. or brake.. and transfer weight to the front of the car.. which will give your front end more traction...

with a powerful enough car.. you could also gas at the same time to power slide the back end out... haha... but probably not a good technique to practice.. haha


i would love to hear some driving instructors inputs though...

I know... from expirience that oversteering on a front wheel drive car is EXTREMELY difficult to regain control. It's not like a RWD where you can counter steer and control the rear end with throttle control...

RWD oversteering.... pretty much what Gerael said. It takes lots of practice.

Front wheel over-steer : What I heard was you should counter steer to the direction of travel. Then you accelerate hard, the front will lurks forward thus will pull back the tail of the car towards the direction of travel.

But for rear wheel drive, I have hear several version, thats why I am not that sure how the correct counter measures.

for me also from driving experience.

RWD? oversteer... i think counter n let go of accel. in real world driving situation if its not an intentional over...

unless u wanto dori dori dorifto

Understeer
Slow down and pray the front regains traction...

RWD oversteer can be caused by overspeeding (momentum causes u to oversteer) or applying too much power to the wheels. Both requires counter steering, for the first one you balance the car by applying throttle, for the latter you have to ease up on the accelerator so the wheels regain traction. After that be ready to steer back otherwise you get yourself in a counter skid. For FWD oversteer, you counter steer but instead of holding the steering angle, u point your steering where you wanna go (after countersteer) and full throttle out. Anyway you have to practise to know how to do it. As for understeer, reduce steering angle a bit to regain front traction, don't lift off the throttle too suddenly.

Oversteer : Counter steer to point the car where you want to go...use the throtle to keep the car in balance, its not something you can learn in a book, its all about feel, also remeber Smooth Input....violent input or jerky movements can cause the car to go out of control. Also IMO make lots of small inputs vs one big input. DONT hit the brakes when the car is in an Oversteer situation...this will cause the weight to lift off the back wheels, resulting in a total loss on control.

My best advice for learing how to control oversteer......drive around in a big wet parking lot.

Understeer : When the cars front tires loose grip it will start to run wide....many people try to counter this by turning the wheel MORE, that will cause MORE understeer...what you want to to is turn less, this will allow the cars tires to regain grip and the car will stop pushing. You have to pay close attention as understeer can overheat tires very quickly. Trail braking (contiuning to apply the brakes after you start to turn into the corner) can help keep the weight on the front and help reduce the cars understeer. What you do with the throtle durring understeer depends on the car : FWD you want to reduce the trotle input, RWD you can do the same OR apply more throtle to help turn the understeer to over steer...just enough will help balance the car, but you still need to make you line wider durring understeer.

That is what i have learned works for me, and what I have learned from driving the car both at autox and track days, as well as Evo and other schools.

Please correct me if im wong.

Yo,

Thank you all for the advices. I think must try it at some big open space car park to get the feel of drifting ........

very nice input KYLIQUID, very well explained.

RWD Oversteer has been well discussed here, but FWD oversteer is a different matter.

To correct FWD oversteer you need to apply gas. This will do 2 things:

1) You will get weight transfer to the rear wheels.
2) By applying throttle you'll be using the front tires to help pull yourself out of the oversteer condition.
