understeer/oversteer

What do f-bodies (3rd gen in particular) NATURALLY do, understeer or oversteer?

Now I know that we can get our oversteer on using the throttle... but all in neutral, bone stock, what's gonna happen after the limits of handling?

Thanks,
-Tesla

Some of that depends on the suspension package your car has. Usually a factory car is set-up to understeer, because it is seen as being safer.

factory sets to understeer, simply reason; the average, and I STRESS average, driver when approaching a corner will slow down when they realize they're too fast for it. Consquently, it's more likely some one will lift off the gas, there by allowing the front to grip better.

Virtually all production cars understeer, partly for the reason Sean listed. Worse yet, the average driver will stab the brakes after they're already into the corner and discover they're too hot. That's a guaranteed recipe for swapping ends and backing into the outer retaining wall if the car is neutral otherwise.

nearly all cars also have roll oversteer built into them though. That is, if you start going around a corner, the body roll acts to increase the steering motion, by way of the geometry of how the inner tie rod ends are placed in relation to the lower control arm bushings. The rod end is made slightly shorter than the effective length of the LCA and its joint is located slightly lower than the LCA pivot point, thus toeing the wheel in slightly when a wheel is pushed up into the fender well and out when the wheel is in "rebound". This makes the car turn in more by itself after the driver turns in and hits the brakes, effectively loosening the car. The combination of these 2 effects makes the car more controllable by an uneducated driver.

Our cars aren't as bad as some about their setup; a stiff rear sway bar loosens the car up quite a bit. That also makes them prone to trading ends, as my little sister found out in my little brother's 84 Z28 one day when some goob malfunctioned in front of her on the x-way. She cut the wheel and stabbed the brakes at the same time, and backed the right quarter into the left retaining wall.

Ok, so what exactly is the "proper" way to take a corner when you are going too fast for it. Slow down enough before, then accelerate through it? Also, what is understeer and oversteer? Thanks ~ Arnold
