Re: Torque Steer
Torque steer is a combination of things. One is the wheels resistance to turning when spinning. Basically, a spinning wheel does not want to turn - if you get a bicycle wheel, holding the ends of the hubs, spin it up to a speed then try turning it left or right - you will notice a resistance to this turning. You dont notice it as much when riding a bike due to the force the handlebars gives you. All cars/wheels get this resistance, so its not torque steer alone, but makes it more noticeable especially if you get wheel spin.
In a front wheel drive, the drive is transmitted to the ground thru the front wheels, very obvious there but important. The components that make that up, including the half shaft and hubs, all want to straighten up under load. This means when using torque, under load, the car wants to steer straight.
It's easy to notice this when under heavy acceleration and turning, such as out of a roundabout. Grab second gear when high in revs, let the clutch out firmly and accelerate hard, and you'll notice its alot harder to keep the steering wheel turned, it wants to kick back to straight.
Another side effect, not included as torque steer but commonly associated with it, is the fact that the car is in an understeer situation. The weight is on the rear wheels as the car accelerates, the front wheels are light, and therefore do not steer as well. As the wheels threaten to, or do, break traction, they no longer provide the lateral traction required to turn the car, so while the steering wheel is turned, the car still propels itself forward and does not turn anywhere near as well.
Hope that helps explain it somewhat.
