When I first took my car to an autox on a sharp right turn, the right tire would just spin and loose traction.  My car is left hand drive so maybe if it was right hand drive that weight would make a difference.  However since I installed the rear sway bar that has changed.  Now I can mash the gas and even pull into the turn tighter and that tire doesn't lose grip.  I'm sold on the sway bar.

Understeer is hitting the wall / tree / object with the front of the car.

Oversteer is hitting the wall /tree / object with the back of the car.

I was always told under steer you see what you run into and over steer what you hit is behind you. Steve  (CTR)

…and now for some snark.

They say that understeer scares the passenger. Oversteer scares the driver.

Corner balancing is the method of adjusting the weight across and diagonally on the car.  It is done with weight in the drivers seat to simulate the driver.  What it does is balance the car so it turns left and right with similar amounts of grip.  My old (72) porsche is just the opposite of the mini.  It wanted to oversteer, (majority of the weight in the back).  After corner balancing, some changes in camber/toe, and the driver learning not to take your foot off the gas in a corner it's a hoot to drive.  

My Classic Mini is just the opposite.  If you take your foot off the gas in a corner it stops turning and goes straight ahead.  I've since added the rear sway bar, which made an incredible difference.  Now tight and decreasing radius turns are the same left and right.

You are thinking maybe about corner weighting. Where you try to balance the weight on each wheel of the car. Usually side to side. Better to look that term up on Google for lots of info. That is just one part of the big picture of car handling.

thanks, there is also something called weight distribution to counter stuff like that, how does that work?

Understeer is when you go off the road on the outside of a corner because your car could not steer enough to go around the corner. Oversteer is when you go off the inside of the corner because your car steered too much and the tail came around.

I want someone to break down the physics for this in simpler terms, basically i get the fact that it has to do with the suspension and the way the tyres and chassis reacts to the external forces but can't quite grasp it
