Do you mean the S2000 or another car?

My S2000 of course. The front away bar is from Muz. A little thicker and a little stiffer than the stock one.

It reduces the front roll in the corner and keep more weight to the rear tires. Especially the the inside rear tire.

Honestly, on the street, a little understeer is safer than having oversteer. It is easier to save the car by lifting the throttle or unwind the steering a little. Sure, it slows you down a bit. But hey, when you are getting understeer in your S2000, you are probably driving too fast.

Just some basics about traction. You have a limited amount of traction and that is true in forward-back and left-right. So if you are using say 95% of you traction accel (almost slipping your tires) and then you decide to make a turn that takes 30% of your total traction, those tires are going to slip. But, it can be on the back tires or the front tires. The same is true under braking, or in any case where you are accelerating; whether that be accel forward, deceleration, or turning. These are all accelerating forces and will change the amount of traction you have at any one point. And at any point if you go beyond 100% of the available traction (which can be different depending on surface, tires, if you are under braking, etc) those tires will begin to slip.

Most of front wheel drive have oversteer..
Since, a FWD car has to use the front wheels for pulling the car down the street and turning a FWD car will almost always exert understeer before it has a chance to oversteer. If you are braking in a corner you can get any car to oversteer. But, unless you have done some pretty crazy stuff to a FWD car they are going to predominately undsteer. He's smoking crack.

In very tight corners, most cars don't have the power to spin the rear tires under hard-acceleration
While it is true, if you are in an understeering condition adding more power will make it worse, but in a tight corner (read: slow corner) it is much easier to brake the rear wheels free cuz you can be in a low gear. In a FWD car braking the driving wheels free will only make you slide more resulting in more understeer.

By giving wider tires on front give less understeer, therfore putting wider tires on rear give more understeer.
I will buy that. Wherever you add more traction is going to result in a change in the dynamic behavior of the car.
Less traction in front == understeer
Less traction in rear == oversteer

so adding traction to the front will lessen the understeer or adding traction to the rear will result in less oversteer.

That is the basics anyway.

To cure that, I used the EDFC to soften the damping at the front and the car feels better coming out of the corner! (shift weight to the front)
